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
Carbonylation of 1-undecene with 13C0 under a hydrogen atmosphere with pa 1 ladi um-s tannous ch 1 or ide cata 1 ys t afforded [ 1-13C Idodecanoi c ( 1 aur i c acid on a 0.25 mole scale. Reduction to the alcohol and treatment with concentrated HBr gave 1-[l-C]bromododecane which was used to alkylate
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,
