Abstract

α-Sulfinyl esters can be readily prepared through thiol substitution of α-bromo esters followed by oxidation to the sulfoxide. Enzymatic resolution with lipoprotein lipase provides both the unreacted esters and corresponding α-sulfinyl carboxylic acids in high yields and enantiomeric ratios. Subsequent decarboxylative halogenation, dihalogenation, trihalogenation and cross-coupling gives rise to functionalized sulfoxides. The method has been applied to the asymmetric synthesis of a potent inhibitor of 15-prostaglandin dehydrogenase.

摘要

α-亚砜酯可以通过α-溴酯的硫醇取代,然后氧化为亚砜来制备。脂蛋白脂肪酶的酶促拆分以高产率和对映体比率提供未反应的酯和相应的α-亚磺酰羧酸。随后的脱羧卤化、二卤化、三卤化和交叉偶联产生官能化的亚砜。该方法已应用于强效 15-前列腺素脱氢酶抑制剂的不对称合成。
