2-methoxymethyl-3-benzyloxy-6-methyl-pyran-4(1H)-one → 2-(1-Methoxyethyl)-3-benzyloxy-pyran-4(1H)-one

Participants

Reaction Steps

In an analogous procedure in the preparation of 2-methoxymethyl-3-benzyloxy-6-methyl-pyran-4(1H)-one using 2-(1-hydroxyethyl)-3-benzyloxy-pyran-4(1H)-one (2.46 g, 10 mmol, 1 eq.) yielded the title compound as a yellow oil (2.4 g, 92.3%). Further purification by column chromatography on silica gel (eluant: EtOAc) furnished the pure product (2.1 g, 80.8%) as a bright yellow oil.
