AI Article Synopsis
- A new compound, p-coumaroyl dimethyl malate (1), was discovered from the leaves of Pandanus amaryllifolius, alongside three related compounds.
- The structures of these compounds were identified using spectroscopic methods, revealing they exist as mixtures of E and Z isomers.
- The study found that the Z isomer likely forms as an artifact during purification of the E isomer, which was confirmed through synthesis experiments.
Article Abstract
A novel p-coumaroyl dimethyl malate (1) was isolated from the Pandanus amaryllifolius leaf in addition to three known analogs of p-coumaroyl dimethyl malate (2-4), and their structures were elucidated by analysis of the spectroscopic data. The p-coumaroyl malate derivatives were isolated as a mixture of E and Z isomers. To determine the cause of isomerization, the p-coumaroyl malate isolated in this study was synthesized. We concluded that the Z isomer might be an artifact generated from the E isomer through purification steps.
