User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a hexacyclic triterpenoid that is D:A-friedooleanan-29-oic acid substituted by a hydroxy group at position 3 and an epoxy group across positions 3 and 24 (the (3beta,20alpha stereoisomer). Isolated from Salacia macrosperma and Tripterygium wilfordii, it exhibits anti-HIV activity. It has a role as a metabolite and a HIV-1 reverse transcriptase inhibitor. It is a hexacyclic triterpenoid, a hydroxy monocarboxylic acid and a cyclic hemiketal. It derives from a hydride of a friedelane.
Assistant: This is a molecule that fits this description: C[C@@H]1[C@@]23CC[C@H]4[C@@](C)(CC[C@@]5(C)[C@@H]6C[C@](C)(C(=O)O)CC[C@]6(C)CC[C@]45C)[C@@H]2CC[C@]1(O)OC3
