glycosyl moiety at the N-1 position, that have the ability to mimic the natural 2'-deoxyribosyl moiety. Some of these potential antiviral compounds included variations at both C-5 and C-6 positions of the uracil base. Other variations of the uracil derivatives were the 6-aza congeners. 4-Amino and 4-methoxy pyrimidine derivatives were also made. Compounds in which the base moiety was substituted by 5-chloro-
A preparative approach towards 1-desazapurines, starting from 4(5)-aminoimidazoles and polyfluoroalkyl-containing 1,3-CCC-biselectrophiles was developed. As a result, a set of fluorinated 1-desazapurines was synthesized. Additionally, a synthetic route to 1-desazapurines bearing a sugar-mimicking group is proposed. imidazoles - pyridines - annulations - fluorine - diketones - regioselectivity
Fluorinated benzofuro[2,3-b]pyridines, benzothieno[2,3-b]pyridines and 9H-pyrido[2,3-b]indoles (α-carbolines) were synthesized via regiospecific pyridine core annulation of a number of fluoro-containing 1,3-CCC-dielectrophiles to benzofuran-2-amine, benzothiophen-2-amine and 1H-indol-2-amine. Based on the 2,4-bis(trifluoromethyl)-9H-pyrido[2,3-b]indole thus synthesized, the preparative approach towards a set of nucleosides and nucleoside mimetics bearing the α-carboline framework was elaborated.
