Synthesis of (+)-Coriolin B from (+)-Precoriolin

Enantiomerically pure (3aS,3bR,4R,6aS,7S)-(+)-3,3a,3b,4,5,6,6a,7-Octahydro-4,7-dihydroxy-3a,5,5-trimethyl-3-methylene-2H-cyclopentapentalen-2-one (4), produced from (S)-(+)-carvone (3), is converted via the epoxides 5 and 7 into (+)-coriolin B (2). - Key Words: (+)-Coriolin B / Triquinans

Stereospecific Total Synthesis of dl-Coriolin and dl-Coriolin B

The total synthesis of the title compounds are described.The starting materials were the enedione 6 and the siloxy diene 27.Cycloaddition of these compounds afforded 28, which was converted to 30.Degradation of enone 30 gave methyl ketone 32, which upon c
