Allyl 6-amino-5-cyano-2-methyl-4-phenyl-4H-pyran-3-carboxylate

Abstract

In the title compound, C17H16N2O3, the 4H-pyran ring adopts a boat conformation. In the crystal, N—H...N and N—H...O interactions link the molecules, forming an infinite ribbon running along the a-axis direction with N—H...N interactions forming centrosymmetric R22(12) graph-set motifs. The allyl side chain is disordered over two sets of sites with occupancies of 0.720 (7) and 0.280 (7).
