pure [2-(2)H(1)](E,E)-farnesyl diphosphate with recombinant patchoulolsynthase (PTS) fromPogostemoncablin afforded a 65:35 mixture of monodeuterated and dideuterated patchoulols as well as numerous sesquiterpene hydrocarbons. Extensive NMR analyses ((1)H and (13)C NMR, (1)H homodecoupling NMR, HMQC, and (2)H NMR) of the labeled patchoulol mixture and comparisons of the spectra with those of unlabeled

The osmate esters (as the di-pyridine adducts) of optically active mono-, di- and tricyclic mono-unsaturated terpenes were prepared for measurements of opticalrotatorydispersion (ORD) and circulardichroism (CD). All the osmate esters of the cyclic olefins examined exhibited a strong Cotton effect in 470 mμ regions and a weak Cotton effect near 600 mμ regions, which were similar to those of the osmate
