Ak. Kaldybaeva et al., Effect of epoxidation of carbocyclic double bonds on conformational flexibility of 1(10)E,4E-germacranolides, CHEM NAT CO, 36(5), 2000, pp. 497-500
The effect of substitution of double bonds by epoxy groups in 1(10)E,4E-ger
macranolides is studied by molecular mechanics. The probabilities of formin
g conformers in the epoxy derivatives are determined Barriers to possible c
onformational transitions are estimated.
