Abstract

2a (65% yield). The reaction must proceed by [2, 3]-sigmatropic rearrangement of selenenate ester 3 to the allyl selenoxide 4, which fragments to diene.'There are several reported examples of allyl selenoxide to selenenate rearrangement^,^,^ but this is the first demonstration of the allyl selenenate to selenoxide conversion.
