The benzylidene acetals obtained by cleavage of the orthobenzoate moiety in myo‐inositol 1,3,5‐orthobenzoate were used to prepare mono‐ as well as di‐deoxy inositol derivatives via their xanthates. The dideoxygenation is a result of intramolecular abstraction of the benzylidene acetal hydrogen and subsequent cleavage of the acetal ring. Such a cleavage does not take place in analogous acetals derived...
Benzyl ethers, ketals and orthoformates were cleaved with Pd(OH) 2 /C in methanol, to generate the corresponding alcohol; carboxylic acid esters were stable under these reaction conditions. Pd(OH) 2 /C in methanol was used for the deprotection of hydroxyl groups during the preparation of sequoyitol via myo-inositol orthobenzoate. This method of deprotection has the potential to be...
