| Abstract: | Previously unknown 5-azolylpyrans were obtained by reactions ofN-acetonyl- andN-phenacylimidazoles, -triazoles, and -tetrazoles with arylmethylenemalononitriles. The structure of 2-amino-3-cyano-6-methyl-5-(5-nitrotetrazol-2-yl)-4-phenyl-4H-pyran was established by X-ray structural analysis.Deceased.Translated fromIzvestiya Akademii Nauk.
