Abstract
Disclosed herein are phosphoric acid esters of myoinositol, which are represented by the following general formula (I): ##STR1## and their salts, as well as a preparation process thereof. The myoinositol derivatives can each be obtained by causing a phosphorylating agent to act on a myoinositol derivative substituted with catalytic reduction removable substituent groups at the positions other than those desired to be substituted by phosphoric acid residual groups and then catalytically reducing the thus-phosphorylated myoinositol.
