2′-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...

Lup-20(29)-en-28-ol-3-one (betulone)

The asymmetric unit of the title compound, C30H48O2, contains two independent mol-ecules, the main difference between them being that the isopropenyl group is rotated by approximately 180°. In each mol-ecule, the fused six-membered rings have chair-chair-chair-chair conformations and the cyclo-pentane ring adopts an envelope conformation with the C atom bearing the hy-droxy-methyl group as the ...

The title compound, C17H21NO2, was synthesized by the reaction of (1R)-(+)-3-benzyl-camphor and hydroxyl-amine. The oxazole ring makes a dihedral angle of 23.42 (16)° with the phenyl ring. The six-membered ring of the norboryl group adopts a boat conformation, whereas each of the five-membered rings of the norboryl group displays a flattened envelope conformation, with the C atom carrying the m...

Positive Relationship between Menstrual Synchrony and Ability to Smell 5α-Androst-16-en-3α-ol

To explore the possibility that compounds which were identified as pheromones in experimental animals mediate human menstrual synchrony, we examined the relationship between menstrual synchrony and the ability to smell putative pheromones, 5α-androst-16-en-3α-ol (3α-androstenol) and 5α-androst-16-en-3-one (5α-androstenone). When we examined menstrual synchrony among 64 women living together in ...
