N-tert-Butyl-5α-androstane-17β-carboxamide
The title compound, C(24)H(41)NO, is a new derivative of the anti-HIV steroid 17β-(N-tert-butyl-amino-carbon-yl)androst-4-en-3-one. There are four rings in the structure and these are trans-fused. The three six-membered rings exhibit chair conformations, while the five-membered ring adopts an envelope conformation.
متن کاملAndrostane-3β,5α,6β,17β-tetrol trihydrate
The title hydrated tetrol, C(19)H(32)O(4)·3H(2)O, was synthesized by stereoselective reduction of the compound 3β,5α,6β-trihy-droxy-androstan-17-one. All rings are fused trans. The organic mol-ecules are connected head-to-tail along the c axis via O-H⋯O hydrogen bonds. Layers of water mol-ecules in the ab plane inter-connect these chains. A quantum chemical ab initio Roothan Hartree-Fock calcul...
متن کاملN-tert-Butyl-3-hydroxy-5-androstene-17-carboxamide monohydrate
In the title compound, C(24)H(39)NO(2)·H(2)O, the A and C rings of the pregnolene derivative sterol adopt chair conformations, with the B ring in a flattened chair conformation and the five-membered ring in an envelope conformation twisted about the C/D ring junction. The N-tert-butyl-carboxamide substituent is equatorial. The 3β-hydr-oxy H atom and one H atom of the water mol-ecule are disorde...
متن کاملN-tert-Butyl-3-mesitylpropanamide
In the title compound, C(16)H(25)NO, the N-tert-butyl-propanamide fragment is essentially planar, with the exception of two C atoms of the tert-butyl group (r.m.s. deviation = 0.005 Å), forming a dihedral angle of 84.09 (10)° with the plane of the mesityl fragment (r.m.s. deviation = 0.002 Å). The crystal packing is stabilized by an inter-molecular N-H⋯O hydrogen bond, which links the mol-ecule...
متن کاملN-tert-Butyl-2-methylpropanamide
The title compound, C(8)H(17)NO, crystallizes with two independent mol-ecules in the asymmetric unit. In the crystal, inter-molecular N-H⋯O hydrogen bonding is observed between neighboring mol-ecules, forming continuous mol-ecular chains along the c-axis direction.
