(2S)-Methyl 2-(4-chlorobenzenesulfonamido)-4-(methylsulfanyl)butanoate
The enanti-omerically pure title compound, C(12)H(16)ClNO(4)S(2), contains a pyramidal N atom with an S-N bond length of 1.6306 (15) Å. Mol-ecules are linked to form chains parallel to the a axis by classical N-H⋯O hydrogen bonding involving a sulfonyl O atom, supported by three weak C-H⋯X inter-actions. (X = S, O).
متن کاملAbsolute configuration of (2S)-4-(4-hydroxyphenyl)butan-2-ol
The title compound, C(10)H(14)O(2), was isolated from the chloro-form extract of Taxus wallichiana Zucc. In the crystal, mol-ecules are linked by inter-molecular O-H⋯O hydrogen bonds, forming sheets parallel to (100). There are weak inter-molecular C-H⋯π inter-actions between the sheets.
متن کاملMethyl 2-acetamido-2-(4-hydroxy-2-methyl-1,3-dioxo-1,2,3,4-tetrahydroisoquinolin-4-yl)-4-methylpentanoate
In the isoquinoline ring system of the title mol-ecule, C(19)H(24)N(2)O(6), the N-heterocyclic ring is in a half-boat conformation. The mol-ecular structure is stabilized by an intra-molecular O-H⋯O hydrogen bond, which generates an S(7) ring motif. In the crystal, mol-ecules are linked via inter-molecular bifurcated N-H⋯(O,O) and weak C-H⋯O hydrogen bonds into a three-dimensional network.

The thia-diazoyl and sulfonyl-benzene rings in the title compound, C(20)H(23)N(3)O(3)S(3), are aligned to the same side of the mol-ecule, forming a twisted 'U' shape [dihedral angle = 77.6 (5)°]. The benzyl-benzene ring is orientated in the opposite direction from the mol-ecule but projects approximately along the same axis as the other rings [dihedral angle between benzene rings = 28.2 (5)°] s...
