Subject Quinic acid

Pollini and colleagues converted D(—)-quinic acid in five steps into a chiral oxime 395, R = H in an enantiomeric pure form and subjected this oxime to a Beckmann rearrangement (equation 161). Even though the reaction lacked selectivity, 395 was useful in the synthesis of the chiral epoxide 396, a key intermediate in the synthesis of (—)-Balanol 397. The same authors also prepared the isomeric epoxide 398. 

We are not aware of any reports about enzymatic transformations of quinic acid in body tissues. This subject evidently needs to be studied further. 

The present review is to be regarded as a continuation of Fletcher s article1 the facts described therein will not be repeated here unless required for the understanding of recent developments. Because of the considerable expansion of cyclitol chemistry, it is not practicable to cover, as Fletcher did, all compounds of the cyclitol group. Only the inositols, the quercitols, and the inosamines, their derivatives, and some closely related compounds will be discussed the tetrahydroxycyclo-hexanes and -hexenes, and quinic and shikimic acids—on which subjects many important papers have appeared—are not reviewed here.3...
