dc.description.abstract | Four new pyrrole alkaloids, methyl 2-[2-formyl-5-(methoxymethyl)-1H-pyrrol-1-yl]propanoate (1), methyl 2-[2-formyl-5-(methoxymethyl)-1H-pyrrol-1-yl]-3-(4-hydroxyphenyl)propanoate (2), dimethyl 2-[2-formyl-5-(methoxymethyl)-1H-pyrrol-1-yl]butanedioate (3), and dimethyl 2-[2-formyl-5-(methoxymethyl)-1H-pyrrol-1-yl]pentanedioate (4), were isolated from the AcOEt extract of the fruits of Lycium chinenseMiller (Solanaceae). The stereogenic center C(2) in the bulky N-alkyl side chain in each of 1-4 seems to hold the H-atoms of nearby CH2 groups, CH2(7) and CH2(3) (if RH), leading to two different chemical shifts in the H-1-NMR spectrum due to their diastereotopic characteristics. In the H-1-NMR data of each of 2-4, the enhancement of HC(2) signal was inhibited by the R group, probably due to steric hindrance, and its chemical shift was influenced by the anisotropy effect. The structures of 1-4 were elucidated by analysis of various spectroscopic data, including 1D- and 2D-NMR. | - |
