Abstract

Under conditions of kinetic control, the cis-diastereoselectivity of the Pictet-Spengler reaction between tryptophan esters and aldehydes can be controlled by varying the size of the ester group; the reaction proceeds in essentially quantitative yield with most aldehydes when conducted in chloroform in the presence of molecular sieves.
