The preparation of t3C-labeled ribonucleosides starting from D-[t3C~]glucose in 45% overall yield is described. The key of this short synthetic way is the dehomologation of di-O-isopropylidene hexofuranose 2 with periodic acid and NaBI-I4 that afforded stereoselectively the labeled ribofuranose deri

D-(1,5,6-13C3)Glucose (7) has been synthesized by a six-step chemical method. D-(1,2-13C2)Mannose (1) was converted to methyl D-(1,2-13C2)mannopyranosides (2), and 2 was oxidized with Pt-C and O2 to give methyl D-(1,2-13C2)mannopyranuronides (3). After purification by anion-exchange chromatography,

Three selectively labeled propynes were prepared either with deuterium or carbon-13 at position 3 and doubly labeled with carbon-13 at positions 1 and 2 by an alkylation reaction from the corresponding labeled or unlabeled monolithio acetylides and dimethylsulfates. Their lithiation with nBuLi gave
