The total syntheses of (–)-gabosine J and its two gabosinol derivatives, the reduced forms of (–)-gabosine J, were achieved by a chiral pool strategy that started from inexpensive and readily available D-mannitol. The desymmetrization of the C2-symmetric tri-O-isopropylidene mannitol through a H2SO4/silica mediated hydrolysis of one of the two terminal ketals and a ring-closing methathesis (RCM) of
