(-)-Monoterpenylmagnolol (3) was synthesized in eight steps from (+)-3, 9-dibromocamphor (4) and the bis (methoxymethy1) ether (22) of 3-(4-hydroxyphenyl)-l-propanol. Fragmentation of an endo-3-aryl-9-bromocamphor (27) provided the correct absolute stereochemistry. In this total synthesis, dissolving metal conditions were developed to reduce enol phosphate and isopropenyl functions without concomitant reduction of an ...
