Samples of [4-2H1]-1-deoxyxylutose (17a) and [2-13C, 4-2H1]-1-deoxyxylulose (17b), have been prepared by modification of known procedures and fed in aqueous solution to twiglets of Eucalyptus globulus

(3-13C)-(4-13C)-,(5-13C)- and (3,4-13C2)-2-oxoglutaric acid were prepared starting from the simple 13C-enriched compounds: ethyl bromoacetate and paraformaldehyde, via a single reaction scheme on the gram scale in high yield.This reaction scheme allows specific 13C enrichment of every carbon position and any combination of positions. (3-13C)-,(4-13C)-, (5-13C), (3,4-13C2) and (15N)-L-glutamic acid were prepared by converting the corresponding 2-oxoglutaric acids via an enantioselective enzymatic conversion.The labelled L-glutamic acids and 2-oxoglutaric acids were characterized by 1H NMR, 13C NMR and mass spectrometry.

Reaction of 2-phenylselenopropanoyl chloride with methyl (triphenylphosphoranylidene)ethanoate yielded methyl 4-phenylselenopenta-2,3-dienoate (3).Distillation of the ester (3) gave dimethyl (E,E)-3',4'-dimethylcyclobut-3'-ene-1',2'-diylidenebisethanoate
