摘要

Abstract Reduction of indolin-2-ones with lithium aluminium hydride (LAH) or diisobutylaluminum hydride (DIBAL) and desulfurization of indoline-2-thiones with Raney-Ni were investigated. Treatment of indoline-2-ones 1 with LAH or DIBAL yield indoles 4 and/or indolines 3 in moderate-to high yield depending on the substituents at N and C (3) of 1. Indoline-2-thiones 2 were desulfurized with Raney-Ni to give indoles 4 and/or indolines 3.
