Stereoselective Iodocyclization of 3-Acylamino-2-methylene Alkanoates: Synthesis of Analogues of N-Benzoyl-syn-phenylisoserine
摘要:
A convenient approach to racemic analogues of N-benzoyl-syn-phenylisoserine was realized via the stereoselective iodocyclization of amides obtained from Baylis-Hillman adducts.

A regiodivergent allylation of N-acylhydrazones with Morita-Baylis-Hillman (MBH) carbonates has been developed, providing α- or γ-allylated products in excellent yields by using different catalysts. The nature of the base catalyst plays a pivotal role in controlling the reaction pathway, allowing regiospecific access to diverse allylic substituted target compounds from identical substrates.
