The preparation of a variety of N-protected indolaldehydes is reported via the reaction of N-protected bromomethylindoles with 2-nitropropane using NaH/DMF.
An efficient method for the synthesis of 1,4-diacylbenzenes has been developed employing bis-tetrabutylammonium dichromate as an oxidant. By this methodology, a series of aldehydes and ketones have been synthesised under mild reaction conditions in moderate yields.
