Applications of the baylis-hillman adducts in organic synthesis: A facile synthesis of [E]-α-cyanocinnamyl alcohols and [E]-α-cyanocinnamic aldehydes

Basavaiah, Deevi,Kumaragurubaran, Nagaswamy,Padmaja, Kisari

, p. 1630 - 1632 (1999)

Aqueous sulfuric acid mediated transformation of the Baylis-Hillman adducts, i.e. 3-aryl-3-hydroxy-2-methylenepropanenitriles, into [E]-α- cyanocinnamyl alcohols and subsequent oxidation with PCC leading to the formation of stereochemically pure [E]-α-cya
