Enol variants of the Cope rearrangement of cis-2,3-divinyl epoxides and the further functionalization of the oxepin nucleus
Chou,White
, p. 157 - 160 (1991)
The Cope rearrangement cis-2,3-divinyl epoxides containing a silyl enol ether or enol triflate leads to 4,5-dihydrooxepins that are functionalized to allow for the further elaboration of the oxepin ring.
