Preparation of Multifunctional Stereodefined Dienes
摘要:
A number of multifunctional 1,3-dienes with defined stereochemistry were prepared by using the products obtained in DABCO-catalyzed condensation reactions of alpha,beta-unsaturated aldehydes with acrylonitrile or methyl acrylate, as substrates for nucleophilic substitution reactions.
