  A novel approach to the synthesis of benzoic and cinnamic acid derivatives with nor-isoprenoid substituents

  摘要：

  A novel strategy for the synthesis of 4-(nor-polyprenyl)-substituted benzoic acids and their esters of the general formula 1 as well as their vinylogs of the type 2, based on the use of terephthalic aldehyde (3) and its tetramethyl acetal (13), is elaborated. The carbonyl groups in dialdehydes 3 and 12 can be selectively involved in the reaction sequences leading to the introduction of both aliphatic and functional substituents in positions 1 and 4 of the benzene ring.
