Electrophilic Olefin Heterocyclization in Organic Synthesis. Formation of d-Lactams by Iodine-induced Lactamization of d,e-Unsaturated Thioimidates
摘要:
The diastereoselective iodine-induced lactamization of delta,epsilon-unsaturated thioimidates (1) accessible from allylation of a dianion of N-benzyl-3-phenylsulfonylpropionamide (3) followed by elaboration gave the substituted delta-lactams (2).
