Hennen, William J. published the artcileSynthesis of 4-substituted 5-amino-2-(β-
Anhydroallonothioate (I; Z = S) and -selenoate (I; Z = Se), prepared by treatment of anhydroallonimidate (I; Z = NH) with H2S and H2Se, underwent cyclocondensation with H2NCH(CN)2, NCCN(NH2)CONH2, or NCCH(NH2)CO2Et to give C-nucleosides II (X = S, R = NH2, R1 = cyano; X = S, Se, R = NH2, R1 = CONH2; X = S, Se, R = NH2, R1 = CO2Et). II (X = S, R = NH2, R1 = cyano; X = S, Se, R = NH2, R1 = CONH2) were further cyclized with H2NCH:NH or HC(OEt)3 to give thiazolo- and selenazolopyrimidine C-nucleosides, e.g., III (X = S, Se). II (X = S, Se, R = NH2, R1 = CO2Et) were converted in 2 steps into tiazofurin and selenazofurin (II; X = S, Se, R = H, R1 = CONH2), resp.
