摘要

The reactions of phosphonate carbanions with carbonyl compounds' to form olefins have become among the most important methods in organic synthesis. Because of the versatility of the technique, various kinds of phosphonates have been developed2 including@-keto phosphonates3 which were often used for the synthesis of naturally occurring compound^.^ While a few reports5 about the synthesis of y, &unsaturated-P-keto phosphonates have ...
