Abstract
Reactions of the alpha-methyl substituted title ylides 2a, 2b with qui none 1 give the unexpected spiro-diastereoisomers 7 and 8 and the acry lates 9. Reactions of the alpha-ethyl and alpha-benzyl substituted yli des 2c and 2d with 1 afford compounds 4, 11 and 13, 14 respectively. R eaction between 1 and the alpha-halogeno substituted ylides 2e, 2f lea ds to formation of the diesters 16a and 16b respectively. All the fuse d furan derivatives obtained are formed via an initial Wittig mono-ole fination of 1 with the ylide used.
