Selective O-methylation of polyhydroxyflavan-3-ols via benzyl carbonates

The flavan-3-ols (+)-catechin and (-)-epicatechin were selectively transformed to their 3′,4′-di-O-methyl- and 5,7-di-Omethyl-ethers respectively via benzyl carbonates. Such a regioselectivity is facilitated by marked differences in the pKa values of the
