[1R-(1 alpha,2 alpha,4 alpha,5 beta,6 alpha,7 alpha)]-4-Benzoyloxymethyl-5,6-dihydroxy-3,8-ioxatricyclo[5.1.0.0(2,4)]octan-5-yl acetate (3-deacetylcrotepoxide) from Kaempferia rotunda Val.
The title compound, C16H16O7, isolated from Kaempferia rotunda rhizomes, features a six-membered cyclohexane ring that adopts a twisted-boat conformation owing to the presence of two adjacent epoxide attachments that lock in four of the six axial positions. The CH3CO2- and HO- substituents occupy eq...
