Methyl 8-oxooctanoate-4,5-d and methyl 12-oxododecanoate-4,5,8,9-d4 were prepared for use as inzermediates in the synthesis of a series of labelled fatty acid methyl esters. Synthesis of the two compounds began with monoozonization and sodium acetate cleavage of 1,4-cyclooctadiene and 1,5,9-~yclodod
## Abstract The synthesis of isotopomers of phenylpyruvic acid, PPA, selectively labeled with hydrogen isotopes in the 3‐position of the side‐chain is reported. Three deuterium or tritium labeled isotopomers of L‐phenylalanine, L‐Phe, i.e. [(3__S__)‐^2^H]‐L‐, [(3__S__)‐^3^H]‐L‐, and doubly labeled
## Abstract Two types of multi‐labelled urocanic acids with stable isotopes, __i.e.__, [3‐^2^H,1′,3′‐^15^N~2~]urocanic acid and [2,3,5′‐^2^H~3~,2′‐^13^C,1′,3′‐^15^N~2~]urocanic acid were synthesized by the enzymatic reaction of DL‐[3,3‐^2^H~2~,1′,3′‐^15^N~2~]histidine or DL‐[2,3,3,5′‐^2^H~4~,2′‐^13
## Abstract A series of 5β‐cholanic acids labeled with deuterium in the A ring were prepared by exchange labeling of the corresponding ketone by column chromatography on deuterated alumina. Factors affecting yield and labeling efficiency are discussed. 5β‐Cholanic acids labeled with ^13^C in the ca
