One-step synthesis of 1-hydroxymethyl-6-aryl-2H-anthra[9,1-bc]furans, 6-benzyl-2-hydroxymethylbenzonitriles, and 3-arylmethyl-4-methylphthalimides
摘要:
Titled compounds were prepared by the reaction of 2-chlorobenzyl alcohol or 2-bromobenzamide with arylacetonitriles in the presence of LDA. A mechanism in terms of an initial tandem rearrangement pathway followed by appropriate cyclization processes is proposed. (C) 1998 Elsevier Science Ltd. All rights reserved.
