The enzymatic oxidation of amino alcohols was studied to address the long-standing problem of product stability. Amino aldehydes, the much sought after and unstable compounds, can be generated under mildconditions when they are immediately protected. Utilizing a range of alcohol dehydrogenases (ADHs) and semicarbazide as scavenger, the enantioselective synthesis of protected amino aldehydes is possible

benzoic and cinnamic acid derivatives, were isolated from the MeOH extract of the leaves of Zanthoxylum rigidum (Rutaceae). The structures of the compounds were determined on the basis of 1D‐ and 2D‐NMR, and MS analysis. It is the first time that a natural cyclic peptide has been isolated from the genus Zanthoxylum.

The present invention discloses methods for producing a carboxylic acid chloride compound which comprises the step of reacting an alkyl-substituted cyclohexyl carboxylic acid with a chlorinating agent in the presence of a specific urea compound. According to this invention, it is possible to produce a carboxylic acid chloride compound which has high reaction speed, and whose product has high purity or high yield. Thus produced carboxylic acid chloride compound is useful as an intermediate for producing D-phenylalanine derivatives which are used as agents for treating diabetes.
