Basnak, Ivan published the artcileNucleic acid components and their analogs. CXCVIII. Synthesis of uracils substituted in the position 5 or 5,6 with alkyl or cycloalkyl groups and their UV spectra, Application In Synthesis of 19030-75-2, the main research area is thiouracil oxidation; uracil cycloalkyl; Claisen condensation formate acetate; catalyst Claisen condensation; cyclization oxoalkanoate thiourea.
Li diazopropylamide, used as a base in the Claisen condensation of alkylacetates and cycloalkylacetates with EtO2CH or EtOAc gave higher yields of β-oxo esters than NaH or NaN(SiMe2)2. Cyclization of the obtained β-oxo esters with thiourea in an alk. medium gave thiouracils I (X = S), which on subsequent reaction with ClCH2CO2H were transformed into uracils I (X = O, R1 = Me, Me2CH, cyclopropyl, cyclobutyl, cyclopentyl, Pr, Me3C; R2 = Me, Me2CH, Me2CHCH2, cyclopropylmethyl, cyclopropyl).
Collection of Czechoslovak Chemical Communications published new progress about Claisen condensation. 19030-75-2 belongs to class pyrimidines, name is 5-N-Propyluracil, and the molecular formula is C7H10N2O2, Application In Synthesis of 19030-75-2.
