To promote atom efficiency in synthesis and to avoid the generation of environmental waste, the use of stoichiometric amounts of condensing reagents or excess substrates should be avoided. In esterification, excess amounts of either carboxylic acids or alcohols are normally needed. We found that the direct condensation of equimolar amounts of carboxylic acids and alcohols could be achieved using hafnium(IV) or zirconium(IV) salts. These metal salts are highly effective as catalysts for the selective esterification of primary alcohols with carboxylic acids in the presence of secondary alcohols or aromatic alcohols. The present methods can be applied to direct polyesterification and may be suitable for large-scale operations.

In the past 50 years, cross-coupling reactions mediated by transition metals have changed the way in which complex organic molecules are synthesized. The predictable and chemoselective nature of these transformations has led to their widespread adoption across many areas of chemical research. However, the construction of a bond between two sp3-hybridized carbon atoms, a fundamental unit of organic chemistry, remains an important yet elusive objective for engineering cross-coupling reactions. In comparison to related procedures with sp2-hybridized species, the development of methods for sp3-sp3 bond formation via transition metal catalysis has been hampered historically by deleterious side-reactions, such as beta-hydride elimination with palladium catalysis or the reluctance of alkyl halides to undergo oxidative addition. To address this issue, nickel-catalysed cross-coupling processes can be used to form sp3-sp3 bonds that utilize organometallic nucleophiles and alkyl electrophiles. In particular, the coupling of alkyl halides with pre-generated organozinc, Grignard and organoborane species has been used to furnish diverse molecular structures. However, the manipulations required to produce these activated structures is inefficient, leading to poor step-and atom-economies. Moreover, the operational difficulties associated with making and using these reactive coupling partners, and preserving them through a synthetic sequence, has hindered their widespread adoption. A generically useful sp3-sp3 coupling technology that uses bench-stable, native organic functional groups, without the need for pre-functionalization or substrate derivatization, would therefore be valuable. Here we demonstrate that the synergistic merger of photoredox and nickel catalysis enables the direct formation of sp3-sp3 bonds using only simple carboxylic acids and alkyl halides as the nucleophilic and electrophilic coupling partners, respectively. This metallaphotoredox protocol is suitable for many primary and secondary carboxylic acids. The merit of this coupling strategy is illustrated by the synthesis of the pharmaceutical tirofiban in four steps from commercially available starting materials.

Stability and impurity profiling of new drug formulations are now receiving great attention in modern pharmaceutical analysis. In this work, a novel stability-indicating HPTLC coupled with densitometric quantification was developed for the simultaneous determination of alfuzosin (ALF) and solifenacin (SOL) along with their degradation products/official impurities. The two drugs were subjected to different stress conditions. ALF was liable to acidic and basic hydrolysis, while SOL was found to be susceptible to basic and oxidative degradation. The obtained degradation products, namely; ALF impurity-D and SOL impurities-A, E and I were then characterized by IR and mass spectrometry. Chromatographic separation was then performed on HPTLC silica plates 60 F254, as a stationary phase, using ethyl acetate: toluene: ethanol: ammonia (5: 2: 3: 0.4, by volume), as a mobile phase. The plates were scanned at 220 nm and visualized by iodine vapor in daylight. Effect of different factors, including the mobile phase composition and the detection wavelengths, were carefully studied to achieve the optimum conditions for chromatographic separation. Calibration curves were constructed over the ranges of 0.8 ? 30.0 mug/band for ALF and SOL, 0.5 ? 15.0 mug/band for ALF imp-D, 0.5 ? 4.0 mug/band for SOL imp-I and 0.75 ? 7.50 mug/band for SOL basic degradation. The method was also exploited for assessment of the two drugs? stability in Solitral capsules under accelerated storage conditions. The proposed method has many potentials of being simple, economic and selective making it an attractive procedure in analyzing not only the two cited drugs but also their impurities.

We previously reported the synthesis and the antimycobacterial activity of 4-(7,7-dimethyl-7H-furo[3,2-f]chromen-2-yl)pyridine. From this result, we sought to design simple synthetic accesses to related structures allowing the preparation of a diverse set of analogues. Two approaches were investigated. From 3-(2-bromo-7,7-dimethyl-8,9-dihydro-7H-furo[3,2-f]chromen-1-yl)propyl acetate, we prepared 2-arylated derivatives via Suzuki-Miyaura reactions between this bromine-bearing compound and various arylboronates. Moreover, and even more simple, we prepared the ((6-hydroxy-2,2,7,8-tetramethylchroman-5-yl)methyl)triphenylphosphonium salt via a selective bromination of 2,2,5,7,8-pentamethylchroman-6-ol. From this salt, a two stage Wittig reaction with an array of activated acids allowed the quick preparation of many analogues. The biological evaluation of the effect of these compounds on the growth of Mycobacterium bovis as well as Mycobacterium tuberculosis pointed out a fourfold improvement of the antimycobacterial properties for one of the compounds made. However, the many analogues which inhibited the growth of M. tuberculosis in the 0.6-5 mug/mL range turned out to be also cytotoxic on VERO cells growth at the same concentration range.

A new photoredox-catalyzed decarboxylative radical addition approach to functionalized cyclobutanes is described. The reaction involves an unprecedented formal Giese-type addition of C(sp3)-centered radicals to highly strained bicyclo[1.1.0]butanes. The mild photoredox conditions, which make use of a readily available and bench stable phenyl sulfonyl bicyclo[1.1.0]butane, proved to be amenable to a diverse range of alpha-amino and alpha-oxy carboxylic acids, providing a concise route to 1,3-disubstituted cyclobutanes. Furthermore, kinetic studies and DFT calculations unveiled mechanistic details on bicyclo[1.1.0]butane reactivity relative to the corresponding olefin system.
