Application of 166591-85-1, New Advances in Chemical Research, May 2021. Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 166591-85-1, Name is 2-(tert-Butoxycarbonyl)-1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid,introducing its new discovery.

Closely related structural analogues of prazosin have been synthesised and tested for inhibition and activation of Transport-P in order to identify the structural features of the prazosin molecule that appear to be necessary for activation of Transport-P. So far, all the compounds tested are less active than prazosin. It is shown that the structure of prazosin appears to be very specific for the activation. Only quinazolines have been found to activate, and the presence of the 6,7-dimethoxy and 4-amino groups appears to be critically important.

New Advances in Chemical Research in 2021. In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 151004-92-1, name is (S)-1,2,3,4-Tetrahydroisoquinoline-1-carboxylic acid, introducing its new discovery. Application of 151004-92-1

Optically pure 1,2,3,4-tetrahydroisoquinoline carboxylic acids are important chiral building blocks in the pharmaceutical and fine chemical industries. However, the existing chemo-enzymatic deracemization method employing d-amino acid oxidase from Fusarium solani M-0718 (FsDAAO) suffers from the requirement for a large excess of a nonselective chemical reducing agent. To explore an alternative method, we envisaged a concurrent biocatalytic oxidation and reduction cascade in one pot. Herein, we report a novel biocatalytic route for the asymmetric reduction of 3,4-dihydroisoquinoline-1-carboxylic acids employing Delta1-piperidine-2-carboxylate/Delta1-pyrrolidine-2-carboxylate reductase from Pseudomonas putida KT2440 (PpDpkA) as a biocatalyst, yielding the corresponding (S)-1-carboxyl-substituted tetrahydroisoquinolines with high conversions and enantiomeric excess (>99% ee). By combining FsDAAO and PpDpkA in one pot, a fully biocatalytic method was demonstrated for the deracemization of a range of racemic 1-carboxyl substituted tetrahydroisoquinolines to produce the corresponding (S)-enantiomers with >99% conversions and >99% ee. Furthermore, preparative-scale biotransformation of racemic 1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid gave the (S)-enantiomer with 89% isolated yield and >99% ee. Taken together, we provide an enantioselective biocatalytic redox cascade method for the one-pot synthesis of enantiopure 1,2,3,4-tetrahydroisoquinoline carboxylic acids.

Decarboxylative coupling of carboxylic acids with activated olefins has been accomplished using visible light photoredox catalysis. The strategic placement of a radical-stabilizing aromatic group at the beta-position of the olefin component biases the regioselectivity of the addition, allowing reliable, facile access to anti-Michael-type products from readily available precursors. The scope of this methodology was demonstrated with a range of carboxylic acids and appropriately substituted olefins and was applied toward a two-step synthesis of the antiarrhythmic agent encainide.
