(2S,4′R,5′R)-(E)-tert-Butyl 2-acetyl-2-(2-oxo-5-phenyl-1,3-dioxolan-4-ylmethyl)-5-phenylpent-4-enoate
The title compound, C(27)H(30)O(6), was prepared by monodihydroxy-lation of the bis-olefin (E,E)-tert-butyl 2-acetyl-2-cinnamyl-5-phenyl-pent-4-enoate using standard Sharpless asymmetric dihydroxy-lation conditions, followed by treatment with 1,1'-carbonyl diimidazole. In the crystal structure, the phenyl rings form an intra-molecular edge-to-face C-H⋯π contact with an inter-planar angle of 56....
متن کامل4-(5-tert-Butyl-1,3-dithian-2-yl)-5-chloro-2-phenyl-1,3-oxazole
In the title mol-ecule, C(17)H(20)ClNOS(2), the phenyl and oxazole rings are nearly coplanar with an average deviation of 0.022 Å from the mean plane (M). The 1,3-dithiane ring adopts a chair conformation and is twisted in such a way that the C-C(Bu) fragment lies in M (deviations are 0.031 and 0.010 Å, respectively, for the two C atoms).

In the title compound, C(14)H(17)ClN(2)S, the dihedral angle between the planes of the thia-zole and chloro-phenyl rings is 88.86 (3)°. In the crystal, inversion dimers occur, linked by pairs of N-H⋯N hydrogen bonds.
متن کاملMethyl (Z)-3-({5-[(E)-(tert-butylamino)methylidene]-4-oxo-4,5-dihydro-1,3-thiazol-2-yl}sulfanyl)prop-2-enoate
In the title compound, C(12)H(16)N(2)O(3)S(2), the S-vinyl, and tert-butyl-enamine fragments make dihedral angles of 14.19 (2) and 0.85 (2)°, respectively, with the thia-zole ring. In the crystal, mol-ecules are linked into chains with graph-set motifs C(5) along [100] by C-H⋯O inter-actions. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond.
متن کامل5-tert-Butyl-2-[5-(5-tert-butyl-1,3-benzoxazol-2-yl)-2-thienyl]-1,3-benzoxazole
The title compound, C(26)H(26)N(2)O(2)S, was prepared by the reaction of thio-phene-2,5-dicarboxylic acid and 2-amino-4-tert-butyl-phenol. One of the tert-butyl groups is disordered over two conformations, with occupancies of 0.539 (1) and 0.461 (2). The two 1,3-benzoxazole rings are almost planar, with dihedral angles of 0.83 (18) and 1.64 (17)° between the five- and six-membered rings. The th...
