alpha-Trichloromethylation of tertiary amines with trimethyl(trichloromethyl)silane by oxidative coupling, using DDQ as an oxidant, has been realized. The reaction is instantaneous, is scalable, and tolerates a broad range of functional groups and heteroarenes. The trichloromethylated products can be easily converted into beta,beta-dichloroamines, enamines, and alpha-amino acid esters under operationally simple conditions. This methodology provides an efficient alternative to the poisonous cyanation reactions for the synthesis of carboxylic acid and their derivatives.

A mild, practical protocol for the decarboxylative alkylation of heteroarenes has been accomplished via iron photocatalysis. A diverse range of carboxylic acids readily undergo oxidative decarboxylation and then couple with a broad array of heteroarenes in this transformation. The photoexcited state lifetimes of iron complexes are typically much shorter than those of iridium and ruthenium complexes. Here we describe our effort on iron photocatalysis by utilizing the intramolecular charge transfer pathway of iron-carboxylate complexes.

Ruthenium(II) hydride complexes bearing a pyrazolyl-(2-indol-1-yl)-pyridine ligand were synthesized and structurally characterized by NMR analysis and X-ray single crystal crystallographic determinations. These complexes efficiently catalyzed acceptorless dehydrogenation of N-heterocycles and secondary alcohols, respectively, exhibiting highly catalytic activity with a broad substrate scope. The present work has established a strategy to construct highly active transition metal complex catalysts and provides an atom-economical and environmentally benign protocol for the synthesis of aromatic N-heterocyclic compounds and ketones.

An efficient and high yield process for sp3 C-H bond functionalization of N-aryl-1,2,3,4-tetrahydroisoquinolines is disclosed. This involves a visible light mediated photoredox Ugi-type reaction with carboxylic acids and isonitriles under aerobic conditions, employing Ru(bpy)3Cl2 as a photoredox catalyst and CH3CN as the solvent. CH3CN was found to be crucial for the process, and good to excellent yields were achieved for a wide variety of N-aryl-1,2,3,4-tetrahydroisoquinolines, carboxylic acids, and isonitriles. The developed methodology is attractive for the synthesis of a library of 1,2,3,4-tetrahydroisoquinolines. This journal is

(S)-(+)-1-Phenyl-1,2,3,4-tetrahydroisoquinoline, which is the key intermediate in preparing the urinary antispasmodic drug solifenacin, was racemized in quantitative yield by a simple one-pot procedure through N-chlorination with trichloroisocyanuric acid, conversion of the N-chloroamine into the imine hydrochloride, and reduction of the imine double bond. The racemized amine was successfully resolved by d-(-)-tartaric acid obtaining (S)-1-phenyl-1,2,3,4-tetrahydroisoquinoline in 81% yield and with 96.7% ee and, from the crystallization mother liquors, the R enriched form. This was racemized by the same one-pot process and resolved by d-(-)-tartaric acid with the same efficiency. Such an approach to the racemization of 1-phenyl-1,2,3,4- tetrahydroisoquinoline can be industrially useful to recycle the waste R enantiomer resulting from the classical resolution used to obtain the S enantiomer on a large scale.

A mild and metal-free DEAD-promoted (DEAD = diethyl azodicarboxylate) oxidative Ugi-type reaction of tertiary amines has been demonstrated. The reaction gives easy access to alpha-amino amides and imides with diverse functional groups in good isolated yields. This Ugi-type approach achieves an unprecedented synthesis of alpha-amino amide analogues with the assistance of dicarboxylic acids, and not water, for the introduction of the carbonyl oxygen atom of the amide moiety. Mechanistic studies indicated that the dicarboxylic acids may readily undergo an intramolecular annulation, instead of the Mumm rearrangement, to give the desired amide with one molecule of anhydride released.

Computed Properties of C15H19NO4, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.166591-85-1, Name is 2-(tert-Butoxycarbonyl)-1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid, molecular formula is C15H19NO4.

Various alkyl radicals generated by the photoreaction of a series of Barton esters reacted with 1,1-dichloro-2,2-difluoroethene to give radical adducts as the major product accompanied with self-trapping products. Primary, secondary, tertiary, benzyl, and some unsaturated alkyl radicals as well as those with another functional group such as ether, carbonyl, and azide were applicable. Barton esters of diacids also afford 1:2 adducts with a small amount of 1:1 adducts and bis-self-trapping products except for the succinic case. These adducts were hydrolyzed with AgNO3/H2O-THF to alpha,alpha-difluoroalkanecarboxylic acids and methanolyzed with AgNO3/MeOH to the corresponding methyl esters. 4-Azido-2,2-difluorobutylic acid and the methyl ester were converted to difluoro-GABA and difluoro-gamma-lactams.

A set of benzimidazole derivatives bearing on position 2 a tetrahydropyranyl or tetrahydrofuranyl residue was prepared and tested for antitumoral, anti HIV-1 and other pharmacological activities. While the anti-HIV activity was completely lacking, moderate antitumoral activity was found in a few compounds; particularly the 5,6-dichloro-2-(tetrahydropyran-2-yl)-benzimidazole (8) was able to inhibit the growth of 19 cell lines of humane tumors at near micromolar concentration. On the other hand compounds 4, 6-8 and 10 exhibited significant tracheal relaxant activity in vitro at concentration 3-10 mug/ml, thus resulting superior to theophylline and comparable to amrinone.
