The new compounds include the E-and Z-isomers of 12,15-dihydroxylabda-8(17),13-dien-19-oic acid, the E- and Z-isomers of 2α-hydroxycommunic acid as well as 15,16-bisnor-8,17-epoxy-13-oxolabd-11E-en-19-oic acid, whose structures were determined by spectral methods. An epoxy communic acid, 12,13-epoxylabda-8(17),14-dien-19-oic acid and the isomer of dihydroxy communic acid, 12,13-dihydroxylabda-8(17),14-dien-19-oic acid, were isolated for the first time from a natural source. © 1993. |
