摘要

摘要三聚体咖啡酸衍生物pulcaffeate(1)是从波兰科波兰根有机粗提物中分离得到的。1的生物合成似乎涉及环己-1,3-二烯中间体(由肉桂酸单元的芳香环氧化产生)和咖啡酸单元的共轭双键之间的分子内Diels-Alder反应。通过对其1H和13C NMR数据的详细分析,阐明了新代谢物的结构。这是首次报道一种三聚体代谢物出现在白杨中。Resumen。蒲草科(1)蒲草科(1)蒲草科(1)蒲草科(1)蒲草科(1)蒲草科(1)蒲草科(1)蒲草科(1)蒲草科(1)蒲草科(1)蒲草科(1)蒲草科(1)蒲草科)La biosíntesis de 1 parece llevarse a cabo mediante una reacción分子内de Diels-Alder中心和中间体de cyclohexa-1,3-dieno, generado durante La oxidación del anillo aromático de una unidad de ácido cinámico, el双链共轭物de una unidad de ácido cafeico。La structure del nuevo metabolito futureelucidada mediante el análisis detallado de sus datos espectroscópicos de RMN de 1H y 13C。Este和el primer报道了在B. pulchra中有明显的代谢性trimica存在。

Pulcaffeate, a Trimeric Caffeic Acid Derivative from Bourreria pulchra
Abstract. The trimeric caffeic acid derivative pulcaffeate (1) was isolated from the organic crude extract of the roots of Bourreria pulchra (Boraginaceae). The biosynthesis of 1 appears to involve an intramolecular Diels-Alder reaction between a cyclohexa-1,3-diene intermediate, generated by the oxidation of the aromatic ring of a cinnamic acid unit, and the conjugated double bond of a caffeic acid unit. The structure of the new metabolite was elucidated through a detailed analysis of its 1H and 13C NMR spectroscopic data. This is the first report of a trimeric metabolite occurring in B. pulchra.   Resumen. Pulcafeato (1) un derivado trimérico del ácido cafeico fue aislado del extracto orgánico crudo de las raíces de Bourreria pulchra (Boraginaceae). La biosíntesis de 1 parece llevarse a cabo mediante una reacción intramolecular de Diels-Alder entre un intermediario de cyclohexa-1,3-dieno, generado durante la oxidación del anillo aromático de una unidad de ácido cinámico, y el doble enlace conjugado de una unidad de ácido cafeico. La estructura del nuevo metabolito fue elucidada mediante el análisis detallado de sus datos espectroscópicos de RMN de 1H y 13C. Este es el primer reporte sobre la presencia de un metabolito trimérico en B. pulchra.

期刊介绍: The Journal of the Mexican Chemical Society (J. Mex. Chem. Soc.) is a scientific, blind, peer reviewed, and open access, free of charge publication that covers all areas of chemistry and its sub-disciplines (i.e. medicinal chemistry, natural products, electrochemistry, material science, computational chemistry, organic chemistry, bionirganic chemistry, etc). It is devoted to facilitating the worldwide advancement of our understanding of chemistry. It will primarily publish original contributions of research in all branches of the theory and practice of chemistry in its broadest context as well as critical reviews in active areas of chemical research where the author has published significant contribution. The J. Mex. Chem. Soc. is a quarterly publication which language of submission and publication is English. To be suitable for publication in J. Mex. Chem. Soc., manuscripts must describe novel aspects of chemistry, high quality of results and discussion an excellent bibliographic support, and contribute to the development of the field. Routine or incremental work are not suitable for publication in J. Mex. Chem. Soc. Authors are encouraged to send contributions in electronic form. Our online submission system guides you stepwise through the process of entering your article details and uploading your files.
