A facile synthesis of a wide variety of tert-butyl ethers and tert-butyl ester derivatives under mild conditions is described. Alcohols etherified with tert-butyl methyl ether as tert-butyl source and solvent, in the presence of sulfuric acid. Many amino acid tert-butyl esters have been synthesized by this procedure. The reaction is simple, inexpensive, easily scaled up, and proceeds without observable
描述了在温和条件下容易地合成多种叔丁基醚和叔丁基酯衍生物。在硫酸存在下,用叔丁基甲基醚作为叔丁基源和溶剂将醇醚化。通过这种方法已经合成了许多氨基酸叔丁酯。该反应简单,廉价,易于放大,并且进行时没有明显的外消旋作用。开发了一种绿色方法,用于使用Amberlite树脂IR 120-H作为催化剂对该基团进行脱保护。
