A Novel Synthesis of 3-O-Allyl-4, 5, 6-tri-O-benzyl-1-O-(p-methoxybenzyl)-D-myo-inositol

Highly efficient synthesis of the entitled compound was achieved from a readily available myo-inositol derivative. The key step involved a desymmetrization with (+)-camphor dimethyl ketal to give two diastereomers. The two diastereomers could be used to synthesize the same compound by changing the orders to introduce the protective groups.
