Synthesis, reactions and applications of pyranotriazolopyrimidines
Get PDFThis review deals with synthesis, reactions and their applications of pyrano triazolo pyrimidines. The main purpose of this review is present a survey of literatures on the reactivity of amino imino derivatives and carboxylic acid derivatives. Some of these reactions have been applied successfully to the synthesis of biological important compounds
Ethyl 6-amino-5-cyano-4-isopropyl-2-methyl-4H-pyran-3-carboxylate
Get PDFIn the title compound, C13H18N2O3, the two H atoms of the NH2 group are engaged in hydrogen bonding with the N atom of the cyano group and with one O atom of the ethoxycarbonyl group, building a chain parallel to the [100] direction. The N—H⋯N hydrogen bonds assemble the molecules around inversion centres, forming dimers with an R
