摘要
Two di-C-13-labeled farnesyl diphosphates (2 and 4) have been prepared using modified versions of the isoprenoid triflate route previously developed in this laboratory. The (3)J(CC) coupling constants far the precursor alcohols 1 and 3 are 1.6 Hz and 3.6 Hz, respectively, in CDCl3, and very similar results were obtained for 2 and 4 in D2O. This indicates a skew or gauche conformation about the C-3-C-4 bond and a trans conformation about the C-4-C-5 bond in both farnesol and FPP. (C) 1998 Elsevier Science Ltd. All rights reserved.
