Total synthesis of polyprenylhydroquinols and benzoquinones. The total
synthesis of polyprenylhydroquinols and benzoquinones is described. F
irst, ho appropriate aromatic allyl carbonates (moieties with one and
two prenyls) and two activated bifunctional terpenyl derivatives (moie
ties with two and three prenyls) were synthesized. These molecules wer
e then reacted together using a highly regio- and stereoselective coup
ling with Pd(PPh(3))(4) as a catalyst. The synthesis was achieved by f
unctional group elimination and formation of quinonic and hydroquinoni
c moieties.
