The Crystal Structure of 3-(4'-Methoxyphenyl)propanoyl pyrrole of Piper lolot C.DC from Vietnam

C14H15NO2 (293K): monoclinic space group P21/n, a = 24.580(10), b = 5.536(2), c = 9.037(3) Å, β= 91.18(4)°, V = 1229.4(8) Å3, Dx = 1.239 gcm-3, Z = 4, F(000) = 488, lambda(CuKα) = 1.5418 Å, µ= 0.667 mm-1. The title compound which was isolated from the rhizomes of Piper lolot C.DC has antibacterial activity. Its chemical identity was established by this X-ray analysis. The molecule consists of a planar propanoyl pyrrole and a methoxyphenyl fragment with an interplanar angle of 93.8(3)° which is by 30° larger than the corresponding angle reported in the literature for the comparable dimethoxy derivative, which was also derived from Piper species.

Keywords: crystal structure, piper lolot
