Abstract
A unified convenient strategy for the synthesis of 5,6-dihydroxyindole-derived 2,7'-, 2,2'-, and 2,3'-biindolyls (e.g. I) is reported, which is based on proper manipulation of key o-ethynylaniline precursors. By the same methodol. 5,6-diacetoxy-7-iodoindole can also be obtained in good yield.File in questo prodotto:
