An effective and enantioselective process for the total synthesis of (+)-brefeldin A (1) is described which start8 from the dextrorotatory ketone 2. Bmfeldin Al (1) has long been known to exhibit an extraordinary range of biological activities including antibiotic, antiviral, cytostatic and antimit
A formal synthesis of (+)-brefeldin A has been achieved v/a stereoselective construction of hydroxycyclopentane skeleton possessing the requisite hydroxyheptenyl side chain. The highly advanced intermediate 2 has been synthesized from the known Weinreb amide in 19 % overall yield of 11 steps.
A key intermediate, a substituted cyclopentanonitrile (10) with correct stereochemistry. was prepared from D-mannitol and converted to the Corey's intermexate (27) without a C15-epimer, which was finally transformed to (+)-brefeldin A. (+)-Brefeldin A (l), is;La:ed from a variety of fungi by several
