Nitroaldol (Henry) reaction of 2-oxoaldehydes with\ud nitroalkanes as a strategic step for a useful, one-pot\ud synthesis of 1,2-diketones

摘要

The nitroaldol (Henry) reaction of 2-oxoaldehydes with a variety of\udnitroalkanes, under basic heterogeneous conditions and microwave\udirradiation, affords 1,2-diketones in a one-pot way. The key step of the\udprocess involves the nitrous acid elimination from the nitroalkanol\udintermediates instead of the standard water elimination.
