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
## Abstract Tumoral pancreatic islet cells of the RIN5mF line were incubated for 120 min in media prepared in ^2^H~2~O and containing Dβ[1β^13^C]glucose, and Dβ[2β^13^C]glucose, and Dβ[6β^13^C]glucose. The generation of C~2~β and C~3~β deuterated lactic acid was assessed by ^13^C NMR. The interpret
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,
