Lock, Ralf,Waldmann, Herbert
, p. 2753 - 2756 (2007/10/03)
Schiff bases derived from tryptophan methyl ester react with differently substituted electron-rich siloxy dienes in the presence of achiral or chiral boric acid esters to give enaminones 5 and 6 with high diastereomer ratios (up to >98:2). These intermedi
