Synthesis of 3-(D-lyxofuranosyl)pyrazoles by trifluoroacetic acid-catalysed cyclodehydration of 3-(D-galacto-pentitol-1-yl)pyrazoles

New 3-(D-galacto-pentitol-1-yl)pyrazole derivatives have been obtained by the reaction of D-galactose hydrazones and nitroalkenes.Cyclodehydration of the 1-methyl-3-(D-galacto-pentitol-1-yl)pyrazoles in trifluoroacetic acid at room temperature afforded go

Cyclodehydration of 3-(D-manno-pentitol-1-yl)pyrazoles: synthesis of 3-(D-arabinofuranosyl)pyrazoles

Several 3-(D-manno-pentitol-1-yl)pyrazoles were cyclodehydrated by treatment with boiling aqueous 10percent trifluoroacetic acid.The products were α,β-mixtures of 3-(D-arabinofuranosyl)pyrazoles in which the β-anomer was the major component.The structures and configurations of these C-nucleoside analogues were assigned on the basis of their analytical and spectral data, and those of the triacetates.
