✦ Synopsis

Slloxy substituted methyl cyclopropanecarboxylates are cleaved by bromine to afford *-bromo-r-oxoester and, after treatment with tnethylamine, good yields of ol,bunsaturated r-oxoesters Many macrollde antibiotics incorporate the roxocrotonate block l-3 . In addition, the more general type of e,R-unsaturatedr-oxoester 2014 Scheme II: p Me3s'f2cH3
