A facile strategy for the preparation of A-ring fused pyridosteroids has been accomplished in high yields by the reaction of Vilsmeier reagent (chloromethyleneiminium salt) with steroidal A-ring enamides (2- and 3-ene) under thermal conditions. The structure of 6'-chloro-5 alpha-cholest [3,2-b]pyridine was determined by X-ray analysis. (c) 2008 Elsevier Inc. All rights reserved.

Semicarbazones, Phenyl hydrazones, 2,4-DNP and Oxime derivatives are converted into corresponding carbonyl compounds, mostly in quantitative yield by stannous chloride-silica gel. This has general application to various nitrogeneous derivatives.
