The Acrylamide Moiety as an Activated Alkene Component in the Intramolecular Baylis-Hillman Reaction: Facile Synthesis of Functionalized α-Methylene Lactam and Spirolactam Frameworks
A facile strategy for the intramolecularBaylis–Hillmanreaction by utilizing an acrylamidemoiety as an activatedalkenecomponent was developed, which thus provides a convenient protocol for obtaining five- and six-membered α-methylenelactam and spirolactam derivatives.
