A method for producing trans-bis(aminomethyl)cyclohexane includes a trans-isomerization step in which cis-dicyanocyclohexane is isomerized into trans-dicyanocyclohexane by heating dicyanocyclohexane containing cis-dicyanocyclohexane in the presence of a tar component produced by distillation of dicyanocyclohexane; and an aminomethylation step in which trans-dicyanocyclohexane produced by the trans-isomerization step is allowed to contact with hydrogen to produce trans-bis(aminomethyl)cyclohexane.

An improved process for the hydrolysis and purification of an alkoxylated polyol containing a ketal protective functionality, and which may be employed to prepare reduced calorie esterified alkoxylated polyol fat mimetics useful in cooking and in food compositions, comprises contacting an aqueous mixture of the protected alkoxylated polyol with an acid to hydrolyse and thus deprotect the alkoxylated polyol,adding a base to neutralise the acid and cause the mixture to form a first phase containing the deprotected alkoxylated polyol and a second phase containing predominantly water, and separating the phases. The protected alkoxylated polyol may be formed by alkoxylating a protected polyol. The deprotected alkoxylated polyol may subsequently be esterified.

Compounds having the general formula (I): wherein X is S, Se or NH, and stereoisomers thereof, and de-O-sulfonated analogues of all of the foregoing, but excluding naturally occurring kotalanol and de-O-sulfonated kotalanol, and methods for synthesizing same. The compounds are useful as glycosidase inhibitors, and may be used in the treatment of diabetes. The synthetic compounds may also be used as standards in the calibration or grading of natural or herbal remedies produced from natural sources of glycosidase inhibitors such as kotalanol.
