Abstract

Enantiospecific total synthesis of the natural enantiomer of the marine sesquiterpene (-)-4-thiocyanatoneopupukeanane (6) is described. The bicyclo[2.2.2]octanonecarboxylate 11, obtained from (R)-carvone and methyl methacrylate via Michael-Michael reaction, was transformed into bicyclo[2.2.2]octenecarboxylic acid 8. Intramolecular cyclopropanation reaction of the diazo ketone 7, derived from the acid 8, followed by regioselective reductive cyclopropane ring cleavage generated neopupukeanol 20, which was transformed into (-)-4-thiocyanatoneopupukeanane 6.
