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
A synthetic method for the preparation of 2-O-feruloyl-l-malic acid, 2-O-sinapoyl-l-malic acid and 2-O-5-hydroxyferuloyl-l-malic acid from malic acid and ferulic, sinapic, and hydroxyferulic acids, respectively, using Steglich esterification is described.

inhibits the activity of ASIC1a and ASIC3 isoforms, and has a significant analgesic and anti-inflammatory effect. In this work, we described the efficient chemicalsynthesis scheme of sevanol and its analogues, which allows us to analyze the structure–activity relationships of the different parts of this molecule. We found that the inhibitory activity of sevanol and its analogues on ASIC1a and ASIC3

The stereoselectivity of the alkylation of dialkyl malates is dependent on steric hindrance of both ester alkyl groups. It was found that the two alkyl groups have opposite effects on diastereoselectivity. Increased steric hindrance at the C(1) carboxy group increases the anti-selectivity, whereas increased steric hindrance at the C(4) carboxy group decreases it. The results are explained by comparing
