Application of 23190-16-1. Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 23190-16-1, Name is (1R,2S)-(?)-2-Amino-1,2-diphenylethanol. In a document type is Article, introducing its new discovery.
L-piperazine-2-carboxylic acid derived N-formamide as a highly enantioselective Lewis basic catalyst for hydrosilylation of N-aryl imines with an unprecedented substrate profile
L-Piperazine-2-carboxylic acid derived N-formamides have been developed as highly enantioselective Lewis basic catalysts for the hydrosilylation of N-aryl imines with trichlorosilane. The arene sulfonyl group on N4 was found to be critical for the high enantioselectivity of the catalyst. High isolated yields (up to 99%) and enantioselectivities (up to 97%) were obtained for a broad range of substrates, including aromatic and aliphatic ketimines, particularly those with R2 as relatively bulky alkyl groups.
