Method of producing polyisoprenoid compounds by carbon-carbon bond formation
摘要:
A polyisoprenoid compound is prepared by reacting a compound R CH 2 Y wherein Y is lower alkylsulfonyl or arylsulfonyl, and R 1 is isoprenoid or polyisoprenoid, with a XCH 2 R 2 compound wherein X is halogen and R 2 has the same meaning as R', in a polar solvent and in the presence of sodium hydride, potassium hydride, sodium tertiary-alkoxide, potassium tertiary-alkoxide, sodium amide or potassium amide, to obtain a compound
which, in turn, is subjected to a reductive desulfonylation of the group Y, whereby a compound R 1 CH 2 CH 2 R 2 is obtained.
