An x-ray structural study has been made of a compound with the composition C29H44·O5. The bond lengths and valence angles are the usual ones for compounds of this type. All the six-membered rings (A, B, C, and F) have the chair conformation. The five-membered rings D and E have the form of 14α- and 22α-envelopes, respectively. Rings A, B, C, and D are trans… CONTINUE READING
