Ethyl 6-amino-5-cyano-4-isopropyl-2-methyl-4H-pyran-3-carboxyl­ate

In the title compound, C(13)H(18)N(2)O(3), the two H atoms of the NH(2) group are engaged in hydrogen bonding with the N atom of the cyano group and with one O atom of the ethoxy-carbonyl group, building a chain parallel to the [100] direction. The N-H⋯N hydrogen bonds assemble the mol-ecules around inversion centres, forming dimers with an R(2) (2)(12) graph-set motif.

Efficient one-pot synthesis of 6-amino-4-aryl-5-cyano-2-methyl-4H-pyran-3-carboxylates catalyzed by nano MgO in water

Water is a versatile solvent in many ways, and in this sense performing organic reactions in this medium is now of great interest. The one-pot reaction of ethyl acetoacetate or benzyl acetoacetate, with benzaldehydes and malononitrile to provide some novel 6-amino-4-aryl-5-cyano-2-methyl-4H-pyran-3-carboxylates has been performed over nano MgO with high performance in water as a green solvent a...
