A Short, Formal, Biomimetic Synthesis of (±)-Polygalolides A and B
[Image: see text] Reaction of bisacetoxy pyranone 9 with Et(3)N gave 3-oxidopyrylium ylide 10, which underwent a stereo- and regiospecific [5 + 2] cycloaddition with α-methylenebutyrolactone to afford 16 (34%). Treatment of 16 with Cs(2)CO(3) resulted in hydrolysis of the lactone and acetate and con...
