5-Azido-4-benzyloxy-2-methoxy-6-methylperhydropyran-3-ol
In the title compound, C(14)H(19)N(3)O(4), the perhydro-pyran ring adopts a chair conformation. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal packing, mol-ecules are linked by O-H⋯O hydrogen bonds, forming infinite chains along [100].

Straightforward conversion of (+)-6,8-dimethoxy-3,4-dihydro-3- undecylisocoumarin (3) to the title isocoumarin was carried out. Hydrolytic ring opening of (3) afforded the hydroxy acid (4) which was immediately oxidized to keto acid (5) using chromic acid, Cyclodehydration of (5) afforded the 6,8- dimethoxy-3-undecylisocoumarin (6) which on selective demethylation of 8- methoxy group furni...

متن کامل2′-Methylpyrazolo[4′,3′:16,17]androst-5-en-3β-ol
In the title compound, C(21)H(30)N(2)O, there are five fused rings. The A and C rings adopt chair conformations, ring B adopts an 8β,9α-half-chair conformation and ring D adopts a 14α-envelope conformation. The pyrazole ring is planar. Inter-molecular O-H⋯N hydrogen bonds [H⋯N = 1.88 (5) Å] help to stabilize the crystal structure. The absolute structure was deduced from those of the starting ma...
