(3aR,6S,7aR)-7a-Chloro-6-methyl-2-(4-nitrophenylsulfonyl)-1,2,3,6,7,7a-hexahydro-3a,6-epoxyisoindole
In the title compound, C15H15ClN2O5S, the tetra-hydro-furan ring adopts an envelope conformation with the O atom as the flap. The pyrrolidine ring adopts an envelope conformation with the chlorine-substituted C atom as the flap. In the crystal, two types of C-H⋯O hydrogen bonds generate R (2) 2(20) and R (4) 4(26) rings, with adjacent rings running parallel to ac plane. Further C-H⋯O hydrogen b...

The chiral title compound, C(15)H(22)O(5), is an inter-mediate in the total synthesis of biologically active 9,11-secosterols. In the crystal, the cyclo-hexane rings are trans-fused and both adopt chair conformations. In the crystal, mol-ecules are loosely held together in a layer parallel to (100) by weak inter-molcular C-H⋯O hydrogen bonds accepted by carbonyl O atoms of the acetyl groups.

The title compound, C(11)H(22)NO(2) (+)·I(-), is a chiral mol-ecule with five stereogenic centres. The absolute configuration was assigned from the synthesis and confirmed by the structure determination. The central six-membered ring of the indolizine system adopts a chair conformation, with two atoms displaced by -0.690 (2) and 0.550 (2) Å from the plane of the other four atoms. The conformati...
متن کامل(5R,6S)-4-Isopropyl-5-methyl-6-phenyl-3-propanoyl-2H-1,3,4-oxadiazinan-2-one
The title compound, C(16)H(22)N(2)O(3), was synthesized during the course of a study on (1R,2S)-norephedrine-derived 1,3,4-oxadiazinan-2-ones. The conformation adopted by the isopropyl group is pseudo-axial relative to the oxadiazinan core. The allylic strain contributes to this conformational arrangement.

The title compound, C(20)H(27)BrO(4), a 4-bromo-benzoyl derivative of a stereoisomer of glycerol menthonide, synthesized as part of a study of 3-carbon stereochemical moieties, crystallizes with two crystallographically independent mol-ecules in the asymmetric unit, the two mol-ecules differing only in one of the C-O-C-C torsion angles around the ester O atom [-106.5 (7) and 146.1 (6)°]. The tw...
