摘要

We describe an efficient route towards the synthesis of fused bicyclic glutarimides using facile [3+ 3] reaction of α-sulfonylacetamides with different α, β-unsaturated esters as the key step. Intramolecular cyclization of 4-substituted 3-sulfonylglutarimide to form 5, 6-, 6, 6-or 6, 7-fused bicyclic glutarimides was accomplished via alkylation, oxidative cyclization or ring- closing metathesis in modest yield.
