The synthesis of [4,4,4-2H31butanoic acid with 10% yield from deuterated acetic acid is described. The structure is confirmed by n.m.r. and mass spectroscopy and the percentage of labelling is established as >98.5% [2H3lbutanoic acid.
2 3 The preparation of 12,4-HI-and 12,4-HI-tomatidine was accomplished by oxydation of the unlabelled compoun to tomatidone, exchange of and direct reduction of the labelled tomatidone to tomatidine. The efficiency of the procedure was checked by physical (1H and 33C NMR, MS) methods.
