Morita—Baylis—Hillman Reaction and Cyclization of 1‐(p‐Toluenesulfonyl)‐1,3‐butadiene with Aldimines.

Abstract

Amines Q 0120Morita-Baylis-Hillman Reaction and Cyclization of 1-(p-Toluenesulfonyl)-1,3-butadiene with Aldimines. -The title reaction fails with (toluenesulfonyl)butadienes which are sterically more hindered than compound (II), e.g. the 2-, 3-, and 4-methyl-substituted analogues. -(BACK*, T.
