Abstract:

The molecule of title compound, C12H14ClNO3, has an L-shaped conformation, with the methyl propanoate unit at the base. The molecules are linked via O—H...N hydrogen bonds into infinite chains of graph-set motif C(6) running along the b axis. In addition, the structure is further stabilized by C—H...O, C—H...Cl and C—H...π interactions.

Abstract:

In this paper, a new series of ethyl 1-aryl-3-methyl-8-oxo-1,8-dihydropyrano[2′,3′:4,5]pyrimido[6,1-b]quinazoline-2-carboxylate derivatives was synthesised by the cyclisation of methyl anthranilate with ethyl 5-cyano-6-[(ethoxymethylene)amino]-2-methyl-4-aryl-4H-pyran-3-carboxylate derivatives, which were obtained from reaction of triethyl orthoformate with 6-amino-5-cyano-2-methyl-4-aryl-4H- pyran-3-carboxylate derivatives. The title compounds possessed good fluorescence properties. In addition, ethyl 5-cyano-6-[(ethoxymethylene) amino]-2-methyl-4-(p-tolyl)-4H-pyran-3-carboxylate and ethyl 3-methyl-8-oxo-1-(p-tolyl)-1,8-dihydropyrano[2′,3′:4,5]pyrimido[6,1-b] quinazoline-2-carboxylate were further determined by single crystal X-ray diffraction analysis.

Abstract:

Unambiguous syntheses of four unreported monomethylated derivatives of 3-phenyldihydro-1,2,4-triazin-6(1H)-ones, namely, the 1-methyl (2), 2-methyl (3), 4-methyl (4) and the imidic O-methyl derivative (5), are described. Regioselectivity was achieved for the synthesis of (2) by addition of ethyl glycinate to the 1,3-dipolar nitrile imine derived from N- methylbenzohydrazonoyl bromide hydrobromide (8). The key step for the synthesis of (3) was addition of benzyl 3-methylcarbazate (14) to ethyl N-[ chloro (phenyl) methylene ] glycinate (15b). The 4-methyl compound (4) was prepared by cycloaddition of ethyl N-( thiobenzoyl ) sarcosinate (21) with hydrazine hydrate, and the O-methyl compound (5) was prepared by reaction of sodium methoxide with 6-chloro-3-phenyl-4,5-dihydro-1,2,4-triazine (23).

Abstract:

Several 6-substitued-1-methyl-2,5,7,8-tetrahydro-2-thiopyrimido[4,5-d]pyrimidine-4-ones and ethyl 7-amino-5-aryl-1-methyl-4-oxo-1,2,3,4-tetrahydro-2-thiopyrido[2,3-d]pyrimidines-6-carboxylates were synthesized by treatment of 6-amino-1-methyl-2-thiouracil with primary amines and formalin (40%), and with ethyl 3-aryl-2-cyanoacrylate respectively. 8-Substituted-7-hydroxy-3- methyl-2-thioxanthines were synthesized by the treatment of 6-amino-1-methyl-5-nitroso-2-thiouracil with benzylidene-anilines. Elemental and spectral analyses were performed for the new compounds.
