(1R,3S,5R,6S)-6-Acetoxy-3-(4-methylphenylsulfonyloxy)tropane
IN THE TITLE COMPOUND [SYSTEMATIC NAME: (1R,3S,5R,6S)-8-methyl-3-(4-methyl-phenyl-sulfon-yloxy)-8-aza-bicyclo-[3.2.1]octan-6-yl acetate], C(17)H(23)NO(5)S, the fused piperidine ring exists in a chair conformation with the N atom and one C atom displaced by 0.876 (2) and -0.460 (3) Å, respectively, on opposite sides of the mean plane defined by the other four atoms. The fused pyrrolidine ring ad...
متن کامل(2R,6S)-tert-Butyl 2-(benzhydrylcarbamoyl)-6-methylmorpholine-4-carboxylate
The title compound, C(24)H(30)N(2)O(4), was obtained by the reaction of (2R,6S)-4-(tert-but-oxy-carbon-yl)-6-methyl-morpho-line-2-carb-oxy-lic acid with diphenyl-methanamine in dimethyl-formamide solution. The morpholine ring is in a chair conformation. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into chains along the b axis.
متن کامل(6S,7S,8R,8aS)-6-Ethylperhydroindolizine-7,8-diol
In the title compound, C(10)H(19)NO(2), the piperidine and pyrrolidine rings of the perhydro-indolizine ring system adopt chair and envelope conformations, respectively. In the crystal structure, inter-molecular O-H⋯N and O-H⋯O hydrogen bonds link the mol-ecules into a chain running along the a axis.
متن کاملHelical Logic by Ralph C . Merkle
Helical logic is a theoretical proposal for a future computing technology using the presence or absence of individual electrons (or holes) to encode 1s and 0s. The electrons are constrained to move along helical paths, driven by a rotating electric field in which the entire circuit is immersed. The electric field remains roughly orthogonal to the major axis of the helix and confines each charge...
