Abstract
The molecular structure of methyl 1-isopropenyl-5a,5b,8,8,11a-pentamethyl-9-oxo-10-[(E)-1-phenylmethylidene]perhydrocyclopent[a]chrysene-3a-carboxylate II is determined. Compound II С38H52O3 crystallizes in the non-centrosymmetric P21 space group with the cell parameters: а = 11.4450(8) Å, b = 11.1995(8) Å, c = 12.5179(9) Å, β = 93.984(2)°.
