Desai,Gigg,Gigg,Payne
, p. 65 - 79 (2007/10/02)
1,3,4,6-Tetra-O-allyl-myo-inositol was converted into the 2,5-di-O-benzyl- and 2,5-di-O-p-methoxybenzyl ethers, and the products were deallylated to give the 2,5-di-O-benzyl (and p-methoxybenzyl) ethers of myo-inositol, which were converted into the mono-
