Nucleophilic addition of triethylphosphite to 3-acetoxy-2-methylenealkanenitriles and methyl 3-acetoxy-2-methylenealkanoates provides (2E)-2-(diethoxyphosphorylmethyl)alk-2- enenitriles and methyl (2Z)-2-(diethoxy-phosphorylmethyl)alk-2-enoates respectively with good stereoselectivity.

A simple, convenient and one-pot transformation of the acetates of Baylis–Hillman adducts into substituted γ-lactams, that is, (E)-5-alkyl-3-arylidenepyrrolidin-2-ones via treatment with nitroalkanes in the presence of a base, followed by reductive cyclization, using Fe/AcOH, is described.

Reaction of Grignard reagents with methyl 3-acetoxy-2-methylenealkanoates produces (2E)-2-substituted alk-2-enoates, whereas a similar reaction with 3-acetoxy-2-methylenealkanenitriles provides (2Z)-2-substituted alk-2-enenitriles in high (Z)-stereoselectivity.
