Efficient assembly of α-aryl and α-vinyl nitriles via iron-catalyzed ether bond activation
摘要:
A novel and practical method for the synthesis of diverse alpha-aryl and alpha-vinyl nitriles was developed via an iron-catalyzed sp(3) C-O ether bond cleavage with C-C bond formation in the reaction of pi-activated ethers with TMSCN. (C) 2014 Elsevier Ltd. All rights reserved.
primary alcohols. Notably, using ethanol and methanol as alkylating reagents, challenging ethylation and methylation of arylmethyl nitriles were performed. Secondary alcohols do not undergo alkylation reactions. Thus, phenylacetonitrile was chemoselectively alkylated using primary alcohols in the presence of secondary alcohols. Diols provided a mixture of products. When deuterium-labeled alcohol was used
