(R)-N-[(R)-2,2-Dichloro-1-phenyl-2-(phenylsulfonyl)ethyl]-2-methylpropane-2-sulfinamide
The title mol-ecule, C18H21Cl2NO3S2, contains one chiral carbon center and the absolute sterochemistry has been confirmed as as R. An intra-molecular N-H⋯O hydrogen bond occurs and the dihedral angle between the benzene rings is 64.5 (1)°. In the crystal, the mol-ecules are linked by weak C-H⋯O hydrogen bonds, forming a zigzag chain structure extending along the c-axis direction.

The asymmetric unit of the title compound, 2C23H33NO2S·H2O, contains one organic mol-ecule in a general position and one co-crystallized water mol-ecule on a crystallographic twofold axis. Each water mol-ecule serves as a hydrogen-bond donor to a pair of S=O acceptors on symmetry-related mol-ecules. Thus, each trio of mol-ecules forms one title formula unit. These groupings are further connecte...
متن کاملCrystal structures of (R S)-N-[(1R,2S)-2-benzyloxy-1-(2,6-dimethylphenyl)propyl]-2-methylpropane-2-sulfinamide and (R S)-N-[(1S,2R)-2-benzyloxy-1-(2,4,6-trimethylphenyl)propyl]-2-methylpropane-2-sulfinamide: two related protected 1,2-amino alcohols
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...
متن کاملDichlorido[(R,R)-N 1,N 1,N 2-tribenzylcyclohexane-1,2-diamine-κ2 N 1,N 2]copper(II)
In the title compound, [CuCl(2)(C(27)H(32)N(2))], which bears a chiral diamine ligand, viz (R,R)-N,N,N''- tribenzyl-cyclo-hexane-1,2-diamine, the Cu(II) ion is ligated by two N and two Cl atoms in a distorted square-planar geometry. The coordination of the ligands to the Cu(II) ion results in the formation of a five-membered heterocyclic ring and a chiral center at the monosubstituted nitro-gen...
متن کاملNew Large (n, r)-arcs in PG(2, q)
An $(n, r)$-arc is a set of $n$ points of a projective plane such that some $r$, but no $r+1$ of them, are collinear. The maximum size of an $(n, r)$-arc in $PG(2, q)$ is denoted by $m_r(2,q)$. In this paper we present a new $(184,12)$-arc in PG$(2,17),$ a new $(244,14)$-arc and a new $(267,15$)-arc in $PG(2,19).$
