title: Synthesis and absolute stereochemistry of roseophilin.
abstract: The enantiospecific total synthesis of natural roseophilin has been completed in 7.0% overall yield over 15 steps by means of an asymmetric cyclopentannelation. This establishes the absolute configuration of the natural product as 22R,23R. Cyclopentenone (+)-12 was prepared in 78% yield and 86% ee in the key step.
