(S)-Methyl 3-(3,4-dimeth-oxy-phen-yl)-2-[2-(diphenyl-phosphan-yl)benzamido]-propano-ate.

ABSTRACT: Mol-ecules of the title compound, C(31)H(30)NO(5)P, show a sttagered conformation about the C-C bond joining the dimeth-oxy-benzene group to the chiral centre, with the dimeth-oxy-benzene ring gauche to the amide group and anti to the ester group. In the crystal, weak inter-molecular N-H⋯O and C-H⋯O hydrogen bonds form layers parallel to (110).

(S)-Methyl 2-benzamido-3-(3,4-dimeth-oxy-phen-yl)propano-ate.

Project description:The dimethoxypbenzene ring in the title compound, C(19)H(21)NO(5), is gauche to the amide group and anti to the ester group. The chirality was confirmed to be S from two-dimensional NMR spectroscopy. In the crystal, N-H?O and C-H?O hydrogen bonds and several short-contact inter-actions (2.07-3.45?Å) create chains parallel to [110]. The phenyl ring is disordered over two orientations in a 0.54?(2):0.46?(2) ratio.

1-(3,4-Dimeth-oxy-phen-yl)propan-1-one.

Project description:The title compound, C(11)H(14)O(3), was isolated from the stems of Trigonostemon xyphophylloides, which belongs to Trigonostemon genus of Euphorbiaceae. The plants in this genus were used in folk medicine, such as for the treatment of diseases caused by viruses and fungi. The limited investigation of the chemistry of this plant prompted an examination of constituents of its twigs, from which the title compound was isolated. The mol-ecule is approximately planar with an r.m.s. deviation of 0.1237Å. In the crystal, inter-molecular C-H⋯O hydrogen bonds connect the mol-ecules into a two-dimensional network structure with an R(2) (2)(12) graph-set motif.
