T. Murai et al., SYNTHESIS OF ALPHA,BETA-UNSATURATED SELENOAMIDES BY THE CONDENSATION REACTION OF LITHIUM ENESELENOLATE GENERATED FROM SELENOACETAMIDE WITH ALDEHYDES, Synlett, (7), 1997, pp. 775
The reaction of lithium eneselenolate generated from selenoacetamide a
nd LDA with aldehydes gave alpha,beta-unsaturated selenoamides in good
to high yields. The successive addition of n-butyllithium and 3-bromo
-1-propene to alpha,beta-unsaturated selenoamide 3a gave selenoamide 7
with high selectivity.
