本発明によれば、上記の目的は、一般式
[Industrial Application Field] The present invention relates to an esterification catalyst, and more particularly to an esterification catalyst comprising a specific distanoxane derivative. The esterification catalyst provided by the present invention promotes the intramolecular esterification reaction of hydroxycarboxylic acids or reactive derivatives thereof as well as the intermolecular esterification reactions of alcohols or reactive derivatives thereof and carboxylic acids or reactive derivatives thereof. Through these intramolecular or intermolecular esterification reactions, various esters useful as perfumes, pharmaceuticals, polymer additives, liquid crystals, etc. can be obtained. Representative examples of such esters include aroma components of perfumes such as cyclobentadecanolide and ethylene brasileate. [Prior Art] Conventionally, esterification catalysts have been used to promote intramolecular esterification reactions of hydroxycarboxylic acids or their reactive derivatives and intermolecular esterification reactions between alcohols or their reactive derivatives and carboxylic acids or their reactive derivatives. , p-toluenesulfonic acid, sulfuric acid, or bases such as sodium methoxide and potassium t-butoxide.Also, as an alternative to these acids or bases, N,N'-dicyclohexylcarbodiimide-
Condensing agents such as 4-(N,N-dimethylamino)pyridine and triphenylphosphine-2,2'-dipyridyl disulfide are used. In recent years, dibutyl stanoxide [(C 4 H 9 ) 2 SnO]
By using etc. as an esterification catalyst,
It has been reported that the esterification reaction proceeds under conditions close to neutrality [Journal of the American Chemical Society].
the American Chemical Society) Volume 102, No.
See page 7578 (1980)]. [Problems to be solved by the invention] Carboxylic acids, alcohols, or their reactive derivatives having a functional group such as a carbonyl group or an acetal group or a carbon atom-to-carbon double bond in the molecule in the presence of an acid or base When subjected to the esterification reaction described below, chemical changes in the functional groups, migration of double bonds, or geometric isomerization derived from double bonds may occur due to the action of acids or bases. be. Furthermore, the esterification reaction using the above-mentioned condensing agent has the disadvantage that the condensing agent is consumed in an equimolar amount with the carboxylic acid as a raw material. When using the above-mentioned dibutyl stannoxide as an esterification catalyst, the desired ester cannot be obtained in good yield, as shown in the reference examples below. Therefore, the object of the present invention is to carry out an esterification reaction using a carboxylic acid, an alcohol, or a reactive derivative thereof having a functional group or a carbon atom-to-carbon double bond that is susceptible to acid or base. To provide an esterification catalyst that gives a desired ester in good yield without causing chemical change of the functional group, migration of double bonds, geometric isomerization derived from double bonds, etc. It is in. [Means for Solving the Problems] According to the present invention, the above object is achieved by solving the general formula
