<P><B>Abstract</B></P><P>A regioselective synthetic method with which to access 1,3‐tocopheryl glyceride ethers <B>2</B> of diverse carboxylic acids was developed through Bu<SUB>4</SUB>NBr‐catalyzed ring‐opening of tocopheryl glycidyl ether <B>1</B>. Steglich esterification of the 1,3‐tocopheryl acetyl‐glyceride ether <B>2a</B> with various carboxylic acids, followed by selective deprotection of 3‐acetate by LiEt<SUB>3</SUB>BH reduction at –78 °C constitutes a regioselective synthetic method of 1,2‐tocopheryl glyceride ethers <B>4</B>. An example of the differing self‐assembled behavior of phosphorylcholine derivatives <B>6c</B> and <B>7c</B> of 1,3‐ and 1,2‐tocopheryl stearoyl‐glyceride ethers in aqueous solution is also described.</P>
