  (±)-heterocarpine, a hydroxymethylated isoquinoline alkaloid from ceratocapnos heterocarpa

  摘要：

  Heterocarpine, a novel alkaloid from Ceratocapnos heterocarpa, has been characterised as (+/-)-1-hydroxymethyl-2-(3-hydroxy-4-methoxybenzyl)-7-hydroxy-6-methoxy-1,2,3,4-tetrahydroisoquinoline. The alkaloid was synthesized from the corresponding 3,4-dihydro isoquinoliniun salt. A key step in the process is the acid resin catalysed methanolysis of the l-carbamoyl isoquinoline. The structural correlation of the hydroxymethylated alkaloids heterocarpine and malacitanine with their unsubstituted counterparts capnosine and caseamine, also present in the plant, might be of biosynthetic significance.
