A solvent- and metal-free protocol for preparation of N-aryl substituted azacycles from arylamines and cyclic ethers is described. In this method, the combination of POCl3 and DBU is crucial for conversion of arylamines and cyclic ethers to five- and six-membered azacycles. Without solvent, a variety of N-aryl-substituted, five-membered azacycles (pyrrolidines, 2-methylpyrrolidines, and piperidine) and six-membered azacycles (isoindolines and tetrahydroisoquinolines) are synthesized in high yields. This green method provides a sustainable and efficient approach for the preparation of azacycles from various cyclic ethers.

Exploring an alternative anodic reaction to produce value-added chemicals with high selectivity, especially integrated with promoted hydrogen generation, is desirable. Herein, a selective semi-dehydrogenation of tetrahydroisoquinolines (THIQs) is demonstrated to replace the oxygen evolution reaction (OER) for boosting H2 evolution reaction (HER) in water over a Ni2P nanosheet electrode. The value-added semi-dehydrogenation products, dihydroisoquinolines (DHIQs), can be selectively obtained with high yields at the anode. The controllable semi-dehydrogenation is attributed to the in situ formed NiII/NiIII redox active species. Such a strategy can deliver a variety of DHIQs bearing electron-withdrawing/donating groups in good yields and excellent selectivities, and can be applied to gram-scale synthesis. A two-electrode Ni2P bifunctional electrolyzer can produce both H2 and DHIQs with robust stability and high Faradaic efficiencies at a much lower cell voltage than that of overall water splitting.

An oxidative cross-dehydrogenative coupling (CDC) reaction for the formation of C-C and C-P bonds is disclosed using a catalytic amount of DDQ (10 mol %) under aerobic conditions (see scheme). This unprecedented environmentally benign strategy of using AIBN (10 mol %) and molecular oxygen to regenerate DDQ exhibits a larger substrate scope. For the first time, an efficient utility of 4-hydroxycoumarins as pronucleophiles for CDC is presented. Copyright

New discoveries in chemical research and development in 2021. SDS of cas: 118864-75-8, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 118864-75-8, Name is (S)-1-Phenyl-1,2,3,4-tetrahydroisoquinoline, molecular formula is C15H15N. In a Article，once mentioned of 118864-75-8

Oxidation of P4S3 with ICN gives exo,exo- and endo,exo-beta-P4S3I2, -beta-P4S3(CN)2, and -beta-P4S3I(CN) as initial products. Ab initio GIAO calculations of NMR shieldings at the RHF/3-21G* level are sufficient to assign the spectrum of endo,exo-beta-P4S3(CN)2 and to confirm the identity of the observed endo,exo-beta-P4S3I(CN), which has iodine rather than cyanide in the hindered endo position. Reaction of enantiomerically pure (S)-1-phenyltetrahydroisoquinoline with exo,exo-beta-P4S3I2 gives an exo,exo-diamide in which the Cs symmetry of the beta-P4S3 cage is lost. The two amido groups, planar at nitrogen, are each capable of two orientations, giving four P-N bond rotamers at 183 K. The 31P NMR spectra of three of these have been fitted, and assigned to particular rotamers by ab initio shielding calculations.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 118864-75-8, and how the biochemistry of the body works.SDS of cas: 118864-75-8

Azomethine ylides are accessed under mild conditions via benzoic acid catalyzed condensations of 1,2,3,4-tetrahydroisoquinolines or tryptolines with aldehydes bearing a pendent dipolarophile. These intermediates undergo intramolecular [3 + 2]-cycloadditions in a highly diastereoselective fashion to form polycyclic amines with four new stereogenic centers. Challenging substrates such as piperidine, morpholine, and thiomorpholine undergo the corresponding reactions at elevated temperatures.
