Design, Synthesis, and Antifungal Activity of Alkyl Gallates Against Plant Pathogenic Fungi In Vitro and In Vivo

A series of alkyl gallates was synthesized by reacting gallic acid with the corresponding alcohols. Their structures were determined on the basis of spectroscopic data, including NMR and MS. The antifungal activities of these compounds against plant pathogenic fungi in vitro and in vivo were assessed.

Zn(OTf)2-promoted chemoselective esterification of hydroxyl group bearing carboxylic acids

Selective esterification of aliphatic and aromatic carboxylic acids with various alcohols is studied using triphenylphosphine, I2, and a catalytic amount of Zn(OTf)2. Use of this catalyst allows the formation of esters at a faster rate with good to excellent yield by activating the in situ generated acyloxyphosphonium ion intermediate. During the esterification process, both their aromatic and aliphatic hydroxyl groups are fully preserved from transesterification. The results show that the bulkiness and the reactivity of this doubly activated intermediate III control the selectivity and the rate of the reaction, respectively. The method is also useful for direct amidation reactions.

Effect of natural and synthetic benzyl benzoates on calmodulin

The present investigation describes the effect of the spasmolytic benzylbenzoates 1-9 from Brickellia veronicifolia on CaM using a functional in vitro enzymatic assay. Bovine brain PDE1 was used as a monitoring enzyme. The most active natural inhibitors of the system CaM-PDE1 were benzyl benzoates 3-5, which inhibited the activity of PDE1 in a concentration-dependent manner. In addition, three series of analogs of compound 4, compounds 10a-32a, were prepared and assayed. The benzyl benzoates from the first series, namely 10a-24a, possess no substituents on ring B but different number and position of hydroxyl or methoxy groups in ring A. The second group (25-32a), on the other hand, possesses an A ring identical to that on compound 4, but different substituents in Ring B. The most active compounds were 14a, 15a and 30a. These compounds were two to six times more potent than chlorpromazine, a well known CaM inhibitor. Benzyl benzoates 14a and 15a have methoxyl groups at C-2/C-4 and C-3/C-4 in ring A, respectively; while 30a, in addition to the methoxyl groups at C-2/C-6 of ring A, hold a benzoyloxy moiety at C-3′ of ring B. Kinetic studies revealed that compounds 3, 4, 14a, 15a and 30a behave as competitive CaM antagonists.

Galloyl-derived orthoquinones as reactive partners in nucleophilic additions and Diels-Alder dimerizations: A novel route to the dehydrodigalloyl linker unit of agrimoniin-type ellagitannins

Orthochloranil-mediated oxidation of galloyl monoethers furnishes the derived orthoquinones in excellent yield. These reactive electrophiles participate in a variety of nucleophilic addition reactions with heteroatomic and carbanionic partners. In addition, Lewis acid-mediated dimerization of the orthoquinones provides an efficient route to dehydrodigalloyl-type diaryl ether units characteristic of several ellagitannin natural products. The implications for ellagitannin biosynthesis and gallotannin-protein covalent attachment are discussed.
