✦ Synopsis

The metalation of (El-l-(2-chlorovinyl)-or (E)-1-(2-bromovinyl)-4-methyl-2,6,7-trioxabicyclo[2.2.2]octane with tert-butyllithium produced an unsaturated homoenolate anion equivalent which intercepted alkyl halides, aldehydes, ketones, and lactones to afford 8-alkylated or 8-acylated orthoesters, which, in turn, furnished P-substituted acrylate esters.

Among the various three-carbon (d3) synthons 1 of the unsaturated homoenolate type' are various P-substituted acrylate esters 2 in which X = an alkyl group, 2 bromine, 3 a thiophenoxy group, 4 or a pyrrolidyl group. 5 In
