Synthesis of Substituted 2-Amino-5-nitro-4H-pyran-3-carbonitriles. -The reaction of ฮฑ-nitroketone (I) with benzylidenemalononitriles (II) catalyzed by Et 3 N represents the first example of a synthesis of nitropyrans (III) from ฮฑ-nitroketones.
2-Amino-8-oxo-tetrahydro-4H-chromene-3-carbonitriles were synthesized for the first time from a tandem Michael addition - cyclization reaction between cyclohexane-1,2-dione and benzylidenemalononitriles. An enantioselective synthesis of these compounds was achieved in moderate ee values (up to 63% e
