Diastereoselective synthesis of spongian diterpenes. Total synthesis of the furanoditerpene (-)-spongia-13(16),14-diene

An effective diastereoselective synthesis of the marine-sponge metabolite (-)-spongia-13(16),14-diene 1 is achieved starting from S-(+)- carvone via a homochiral phenanthrenone as the key intermediate for the construction of the furan ring system. S-(+)-C

An efficient stereoselective synthesis of stypodiol and epistypodiol

An efficient synthesis of stypodiol (1) and its epimer at C-14, epistypodiol (2), was accomplished starting from (S)-(+)-carvone (7). The synthesis of both epimeric compounds proceeds through common intermediates using an IMDA reaction, a sonochemical Barbier reaction, and an acid- catalyzed quinol-tertiary alcohol cyclization as key synthetic steps.
