Notes:
The crystal structures of two intact limonoids, nimonol,7α-acetyl-17α-(3-furyl)-6α-hydroxy-4α,4β,8β-trimethyl-5α,18α-androsta-1,14-dien-3-one (C28H36O5), and 6-oxonimonol,7α-acetyl-17α-(3-furyl)-4α,4β,8β-trimethyl-5α,18α-androsta-1,14-diene-3,6-dione (C28H34O5), are reported. The molecular features are mostly the same in the two structures; however the orientations of the acetoxy group are different in the two structures. The packing in nimonol is due to O—H...O hydrogen bonds while in 6-oxonimonol it is due to C—H...O hydrogen bonds.
