Biosynthesis of (+)-cubenene and (+)-epicubenol by cell-free extracts of cultured cells of Heteroscyphus planus and cyclization of [2H]farnesyl diphosphates
The absolute stereochemistry of cubenene and epicubenol from cultured cells of Heteroscyphus planus was determined as both (+)-isomers by H-1 and C-13 NMR spectroscopy, GLC using a chiral capillary column, and optical rotations. Incubation of two geometrical isomers of deuteriated farnesyl diphosphate (FPP) with a cell-free extract from cultured cells indicated that both compounds were specifically formed from (2E,6E)-FPP. Gas-liquid chromatography-mass spectrometry (GLC-MS) and H-2 NMR analyses of(+)-cubenene and (+)-epicubenol generated from [1,1-H-2(2)]- and [6-H-2]-FPP confirmed the presence of 1,2- and 1,3-hydride shifts in their formation.
