A facile synthesis of (2E)-, (2E, 4E)-unsaturated amides was achieved via arsonium bromides with high stereoselectivity. Its application to the synthesis of related natural products 4 and 5 is also reported.
Abstract A new one-pot synthesis of α,β-unsaturatedamides with high stereoselectivity by the reaction of aldehydes with bromoacetamides promoted by tri-n-butylphosphine and zinc is described.

A diverse set of functionalized alpha,beta-unsaturated carbonyl compounds were synthesized in good yield by utilizing a very simple one-pot process involving a cross-metathesis between acryloyl chloride and a terminal olefin followed by the addition of a nucleophile.
