1.3- Butadiene reaction with ethyl diazopyruvate

The Cope rearrangement of c/j-di vinylcyclopropanes is thermally allowed and offers an attractive stereoselective approach to cycloheptadienes. Cyclopropanation reactions can be used to prepare divi-nylcyclopropanes, as shown in Scheme 23.120 Reaction of ethyl diazopyruvate with butadiene generated... [Pg.1048]

Oxepin 404 was prepared by the reaction of ethyl diazopyruvate with 1,3-butadiene in 26% yield. The reaction involves a carbene addition to the double bond with formation of a mixture of cis- and trans-2-oxo-2-(2-... [Pg.159]
