Synthesis of arene oxide and trans-dihydro diol metabolites of isoquinoline
Abstract
5,6-Epoxy-5,6-dihydroisoquinoline 9 and 7,8-epoxy-7,8-dihydroisoquinoline 21 were each obtained by multi-step synthetic sequences from 5,6,7,8-tetrahydroisoquinoline 1. The mammalian metabolite, trans-5,6-dihydroisoquinoline-5,6-diol 10 was chemically synthesised by base-catalysed hydration of the isoquinoline arene oxide 9.
