Brønsted acid-catalyzed C–C bond forming reaction for one step synthesis of oxazinanones
摘要:
An efficient Bronsted acid-catalyzed synthesis of oxazinanones (2) from corresponding Boc-imines (1) in one-step has been developed. Oxazinanones are obtained via an unprecedented tandem elimination-cycloaddition reaction. The reaction is remarkably significant given its novelty, mild reaction conditions, simplicity and low cost of the catalyst system. (C) 2011 Elsevier Ltd. All rights reserved.

Exchange of thiophene with D2 and reactions of deuterium-labelled propene and isobutene, followed using a combination of mass spectrometry and microwave spectroscopy, have been used to characterise the catalytic nature of a commercial CoO-MoO3-Al2O3(CMA) catalyst. The results indicate that the activity of partially sulphided CMA, produced by exposure to H2S or by hydrodesulphurization (h.d.s.) of ethanethiol
