Endeavor to discover biorational natural products-based fungicides, two series (26) of novel 1-sulfonyloxy/acyloxydihydroeugenol derivatives (3a–p and 5a–j) were prepared and assessed for their fungicidal activity against P. capsici Leonian, in vitro. Res

A practical direct method for the direct preparation of esters and thioesters from aldehydes is described. Esters and thioesters were synthesized by oxidative esterification and thioesterification via in situ generated acyl bromide intermediates, which were used to react with various alcohols and thiols. The esterification and thioesterification were readily performed in the presence of dibromoisocyanuric acid in dichloromethane, without any metal catalysts and under mild conditions. By using this reaction protocol, various esters and thioesters were prepared in high yields. This effective method offers a promising approach for the facile esterification and thioesterification of aldehydes.

A facile method for the direct synthesis of amides from aldehydes is described. Amide bonds were synthesized by an oxidative amidation in the presence of dibromoisocyanuric acid (DBI). Treatment of aromatic and aliphatic aldehydes with dibromoisocyanuric acid generated acyl bromide intermediates, which were employed to react with a variety of secondary and primary amines to give amides. Through this reaction method, various amides were synthesized directly from aldehydes under mild conditions in high yields and short times. This facile and efficient procedure provides potential strategy for the direct synthesis of amides from aldehydes.

Acid bromides were prepared efficiently from carboxylic acids with readily available ethyl tribromoacetate and triphenylphosphine at room temperature under neutral conditions. The present process is applicable to the preparation of various acid bromides from aromatic and aliphatic carboxylic acids. Aromatic carboxylic acids were found to be more reactive than aliphatic carboxylic acids under reaction conditions.

The kinetics of the methanolysis of benzoyl bromide and eight para- or meta-substituted derivatives in acetonitrile at 25.0 deg C can be analysed in terms of the simultaneous operation of overall second- and third-order processes.In turn, each of these processes can be analysed in terms of the simultaneous operation of two reaction channels, which are proposed to involve a carbonyl addition-elimination mechanism (favoured for electron-withdrawing substituents) and a process (SN2-SN1) proceeding through a loose SN2-type transition state.For the p-methoxybenzoyl bromide substrate, a third reaction channel is observed, but only for the overall second-order process (first-order in methanol), and this is tentatively described as involving electrophilic assistance by a methanol molecule to an ionization (SN1) pathway.
