摘要

The invention of new methods for the construction of fivemembered rings continues to be a problem of considerable importance in organic synthesis. 1 Only a few [4+ 1] annulation strategies have been reported to date, one example being the methodology based on oxyanion and carbanion-accelerated vinylcyclopropane rearrangements developed in our laboratory. 2, 3 In this paper, we now report a stereoselective [4+ 1] annulation strategy for ...
