چکیده
The title compound, C(22)H(32)N(2)O(2)S, was obtained by dehydroxy-lation and deacetyl-ation of 4-{(1S,2S)-2-(benzylhydroxy-amino)-3-methyl-1-[(S)-2-methyl-propane-2-sulfinylamino]but-yl}phenyl acetate, which was derived from reductive crosslinking of nitrone with N-tert-butane-sulfinyl-imine. The crystal structure shows that the mol-ecules are linked by O-H⋯O hydrogen bonds.

A new tetra-dentate chiral Schiff base ligand, C(26)H(30)N(2)O(2), has been synthesized by the reaction of 1-phenyl-butane-1,3-dione with (1S,2S)-(-)-1,2-diamino-cyclo-hexane. The chiral centers in the mol-ecule have the same S configuration, since the absolute configuration was determined by that of the starting reagent (1S,2S)-(-)-1,2-diamino-hexane. The cyclo-hexane ring is in a chair confor...

The title compounds, C22H31NO2S, (1), and C23H33NO2S, (2), are related protected 1,2-amino alcohols. They differ in the substituents on the benzene ring, viz. 2,6-di-methyl-phenyl in (1) and 2,4,6-tri-methyl-phenyl in (2). The plane of the phenyl ring is inclined to that of the benzene ring by 28.52 (7)° in (1) and by 44.65 (19)° in (2). In the crystal of (1), N-H⋯O=S and C-H⋯O=S hydrogen bonds...

The rates for magnetic dipole (M1) transitions Υ(nS) → ηb(n S) + γ, n ≤ n, are compared. The photon energies for allowed (n = n) M1 transitions are very small, so hindered (n < n) transitions could be more favorable for discovering the ηb(1S, 2S). The question then arises whether Υ(2S) or Υ(3S) is a better source of ηb(1S). Whereas one nonrelativistic model favors ηb(1S) production from Υ(2S), ...
متن کاملPharmacological activities of optically pure enantiomers of the x opioid agonist, U50,488, and its cis diastereomer: evidence for three x receptor subtypes
De Costa et al. (FEBS Lett. 223, 335; 1987) recently described the synthesis of optically pure enantiomers of (+)-trans-3•4-dich••r•-N-methy•-N-[2-(•-pyrr••idiny•)-cyc••hexy•]benzeneacetamide (U50,488). In the present study we examined the in vitro opioid receptor selectivity of (-)-(1S,2S)-U50,488, (+)-(1R,2R)-U50,488 and (___)-cis-3,4-dichloro-N-methyl-N-[2-(1-pyrrolidinyl)-cyclohexyl]benzene...
