Abstract
Abstract 2-Hydroxymethylindole reacts with l -dehydroascorbic acid under mild conditions to give (3 R ,3a R ,10c S )-3-[(1 S )-1,2-dihydroxyethyl]-3a,10c-dihydroxy-3a,5,6,10c-tetrahydrofuro[3′,4′:5,6]pyrano[3,4- b ]indol-1(3 H )-one. Its tosyl derivative undergoes cyclization to form a pentacyclic ketal derivative.
