A mild method for the aldolization of N-sulfonylimidates was developed. The reaction proceeds in excellent diastereoselectivity to provide a range of useful β-hydroxyimidates in high yield. The innate reversibility of the reaction is suppressed by the use of a titanium complex as a Lewis acid.

α-Aryl β-hydroxy imidates are efficiently obtained by the four-component reaction of ethyl glyoxylates, aryl acetylenes, sulfonyl azides, and alcohols using a copper catalyst. The developed procedure is characterized by high selectivity, mild reaction con
A facile access to N-sulfonylimidates and their synthetic utility for the transformation to amidines and amides
Yoo, Eun Jeong,Bae, Imhyuck,Cho, Seung Hwan,Han, Hoon,Chang, Sukbok
, p. 1347 - 1350 (2007/10/03)
It is shown that N-sulfonylimidates can be efficiently prepared by a three-component coupling of terminal alkynes, sulfonyl azides, and alcohols with use of a copper catalyst and an amine base. The reaction is characterized by mild conditions, high select
