B(OMe)3 as a nonacidic iminium ion generator in Mannich- and Ugi-type reactions
Tanaka, Yusuke,Hidaka, Kousuke,Hasui, Tomoaki,Suginome, Michinori
, p. 1148 - 1151 (2009)
Mannich-type reactions of aldehydes with secondary amines and a ketene silyl acetal were promoted by trimethoxyborane in DMSO to afford the corresponding β-amino esters in good yields. B(OMe)3 also promoted Ugi-type reactions of aldehydes with
Diarylborinic acid derivatives as a catalytic iminium ion generator in the mannich-type reaction using secondary amines, aldehydes, and ketene silyl acetals
Tanaka, Yusuke,Hasui, Tomoaki,Suginome, Michinori
body text, p. 1239 - 1242 (2009/04/05)
Reactions of secondary amines, aldehydes, and ketene silyl acetals were efficiently promoted by catalytic amounts of diarylborinic acid esters, Ar 2B(OR), affording β-amino esters selectively with no formation of the corresponding β-hydroxy esters. Georg Thieme Verlag Stuttgart.
