摘要
An enantioselective synthesis of the ABC-tricyclic furanochroman core of phomactin A has been accomplished by a gamma-hydroxylation approach. The C ring was established by gamma-hydroxylation of an a-enone. The regioselectivity was optimized by using a strong base with an oxophilic cation (t-BuLi) and a bulky oxygen donor (Davis reagent), which afforded the gamma-hydroxylation product selectively in 63% yield.
