Disclosed herein is a novel process for preparing substituted quinazoline compounds of formula (I) using a hydrogen bonding catalyst.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: catalyst-ligand, you can also check out more blogs about121788-73-6

Synthetic Route of 121788-73-6, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 121788-73-6, Name is N,N’-((1R,2R)-1,2-Diphenylethane-1,2-diyl)bis(1,1,1-trifluoromethanesulfonamide), molecular formula is C16H14F6N2O4S2.

A series of N,P-ligands has been prepared, containing a chiral oxazoline ring and as a second chiral unit a bis(N-sulfonylamino)phosphine group embedded in a diazaphospholidine ring or a cyclic phosphite group derived from TADDOL. These modular ligands are readily synthesized from chiral amino alcohols and chiral 1,2-diamines or TADDOLs. Palladium and iridium complexes derived from these ligands were found to be efficient catalysts for enantioselective allylic alkylation and olefin hydrogenation, respectively.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Synthetic Route of 121788-73-6, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 121788-73-6, in my other articles.

A simple and efficient approach to enantioenriched alpha,beta-disubstituted gamma-butyrolactones has been developed through multifunctional modular organocatalysis in a highly enantioselective (>99% ee) and diastereoselective (>30:1) manner following a one-pot sequential Michael-hemiacetalization-oxidation reaction. The catalytic process has great substrate compatibility, and the products have been transformed to synthetically useful molecules. The methodology has also been applied to the formal synthesis of (+)-Pilocarpine.

The enantioselective Friedel-Crafts addition of indoles to nitro-olefins using chiral hydrogen-bonding bis-sulfonamides as the catalysts has been developed. The reactions, in the presence of only 2 mol% catalyst, generally proceed in high yields and with enantioselectivities up to 64% ee, and the enantiomeric excess can be improved to >98% ee by recrystallization. Various synthetic transformations of the Friedel-Crafts adducts are demonstrated: the nitro group can easily be reduced to the corresponding amine and the product obtained can undergo a stereocontrolled Pictet-Spengler cyclization to give, for example, enantiopure tetrahydro-beta-carbolines. The X-ray structure of the chiral bis-sulfonamides has been determined and based on these structures the mechanism for the stereoselectivity in the reaction is discussed.

The kinetic resolution of beta-Aryl substituted 1,7-dioxo compounds with alpha,beta-unsaturated aldehydes affording enantioenriched beta-Aryl substituted aldehydes as well as densely functionalized cyclohexanes is presented. The two enantioenriched products were obtained in reasonable yields with high diastereo-and enantioselectivities under supramolecular iminium catalysis which activates both the substrates and the reactive intermediates.
