Indole reduction
WebReduction - Benzenoid or heterocyclic rings can be selectively reduced by the indole ring. For instance, zinc/HCl can convert indole to indoline. An acidic medium also results in this type of conversion when indole is catalyzed. Benzene ring is the only one reduced by lithium/liquid ammonia. Medicinal Uses WebIn the current year (2024), Jana and co-workers used DDQ as a key mild oxidant in the chemical transformation of indole derivative 43 into indole-fluorene hybrid 44 in high yield. ... The isolation of cyclized products and the recovery of the reduced DDQ–H 2, which can be readily recycled into DDQ by oxidation with nitric acid, are easy.
