An efficient catalyst free, three-component, cascade approach has been designed and developed for the rapid assembly of unsymmetrical triarylmethane framework. The strategy employed aromatic aldehydes, Grignard reagents, and neutral aromatics as reaction partners, under simple thermal conditions. This process affords very broad scope for all three partners as it is performed in the absence of any external additives. (C) 2016 Elsevier Ltd. All rights reserved.

A new strategy for the synthesis of 3-diarylmethyl indoles was developed through FeCl3 as Lewisacidcatalyzedthree-component aza-Friedel–Crafts reactions of indoles, aldehydes, and tertiary aromatic amines in one-pot. The reactions generated the corresponding 3-diarylmethyl indoles in good yields under mild reaction conditions by using less expensive, readily available, and environmentally benign
