A new safe synthesis of a-nitro ketone salts via alkaline hydrolysis of 2-morpholino-1-nitroalkenes has been developed. The salts were introduced into the reactions of diazotization and heterocyclization. Crystal structures of
new 2-morpholino-1-nitrobut-1-ene and 6-ethyl-5-nitro-4-phenyl-3,4-dihydropyrimidin-2-one have been determined.
