c-5-Hy­droxy-r-2,c-4-bis­(meth­oxy­carbon­yl)-t-5-methyl-t-3-(3-nitro­phen­yl)cyclo­hexa­none

In the title compound, C₁₇H₁₉NO₈ [systematic name = dimethyl 4-hydroxy-4-methyl-2-(3-nitrophenyl)-6-oxocyclohexane-1,3-dicarboxylate], the cyclo­hexa­none ring exhibits a chair conformation. The meth­oxy­carbonyl groups are oriented in opposite directions with respect to the cyclo­hexa­none ring. In the crystal, O—H...O hydrogen bonds links the mol­ecules into chains running parallel to the a axis. These chains are connected by weak C—H...O hydrogen bonds, forming sheets parallel to the ab plane.

16α,17α-Ep­oxy-17β-(1H-imidazol-1-yl)androst-4-en-3-one monohydrate

In the title compound, C₂₂H₂₈N₂O₂·H₂O, rings B and C adopt chair conformations. Ring A adopts an envelope conformation, with the non-fused C atom adjacent to the fused C atom bearing a methyl group as the flap atom. Ring D also adopts an envelope conformation, with the fused C atom not bearing a methyl group as the flap atom. The water mol­ecule links the mol­ecules via O—H...O and O—H...N hydrogen bonds, forming zigzag chains which run parallel to the c axis. Weak C—H...O inter­actions also occur.

Propan-2-yl r-4-(4-fluoro­phen­yl)-3-hy­droxy-c-6-methyl-2-phenyl-4,5-dihydro-2H-indazole-t-5-carboxyl­ate

In the title compound, C₂₄H₂₃FN₂O₃, the cyclo­hexene ring adopts a screw-boat conformation. The fluorobenzene ring attached to the cyclo­hexene ring and the phenyl ring attached to the indazole moiety are inclined to one another by 57.77 (13)°. In the crystal, mol­ecules are linked by O—H...N and C—H...O hydrogen bonds, forming chains with C(5) and C(10) graph-set motifs. There are also C—H...π inter­actions present. The isopropoxycarbonyl group undergoes considerable thermal motion.
