摘要:
Fusion of 2-methylindole with morphinals of substituted salicylaldehydes (in a ratio of 1 : 1) afforded 3-[(2-hydroxyaryl)morpholinomethyl]-2-methylindoles as normal products of the Mannich reaction. In some cases, the reactions with an excess of 2-methylindole resulted in unusual condensation accompanied by the replacement of the OH group by the morpholino group to form bis(2-methylindol-3-yl)(2-morpholinoaryl)methanes.
