A 6-step synthesis of the γ-alkylidenebutenolide lissoclinolide (1; 40 percent yield) is described. The Z-configured C1' = Cγ bond was established by an anti-elimination from dihydroxylactone 10, the trans-configured C3' = C2' bond by a Wittig reaction of ylid Z-15 with (tert-butyldiphenylsilyloxy)acetaldehyde. Digressing from this synthesis (Scheme 7), we obtained compound 2 with the surmised structure of tetrenolin. However, the correct structure of 'tetrenolin' turned out to be the same as lissoclinolide. Compound 1 exhibited moderate antimicrobial activity while 2 did not.
