SmI2‐mediated C‐alkylation of Ketones with Alcohols under Microwave Conditions: A Novel Route to Alkylated Ketones

A novel protocol is developed towards the preparation of alkylated ketones from alcohols in presence of catalytic amount of SmI2 and base with the elimination of water as a single by-product under microwave irradiation conditions. Furthermore, applicability of this methodology to the synthesis of Donepezil and late-stage functionalization in Pregnenolone is also reported. Successful application of this methodology in Friedländer quinolone synthesis using 2-aminobenzyl alcohol and various acetophenones expand the synthetic utility of this protocol.
