摘要：
Regioselective bromination of 14β-hydroxydihydroquinopimaric acid methyl ester in acetic acid and methanol gave the corresponding 16S-bromo-, 19R-bromo-, and 16S,19R-dibromo-14β,20-epoxy derivatives whose structure was determined by X-ray analysis and NMR spectroscopy. The reactions of 16S-bromo ketones with thiourea afforded 2,1,3-thiadiazoles fused to diterpene fragment.
