摘要

A one-pot synthesis of strained heterobicycles such as 2-thia (or 2-aza)-3-iminobicyclo [2.2. 0] hex-5-enes and 2-thia-3-azabicyclo [4.2. 0]~ 7-ene 2-oxides from alkynes, aluminum halides, and heterocumulenes (isothiocyanates, carbodiimides, N-sulfinylaniline) is described. The thermal and acid-promoted reactions of the permethylated 2-thia-3- iminobicyclo [2.2. 0] hex-bene 2 to monocyclic isomers are reported.
