,3]oxathiine-1,1-dioxide has been found to react with several electrophiles, such as various halides and aldehydes, upon regioselective deprotonation. This method utilizes the sulfone group to form new carbon-carbon bonds while serving as a masked carbonyl. Subsequent hydrolysis of the sulfone provides a facile approach toward many useful synthetic intermediates. This methodology could provide a useful
(2-Butyl-4,4-dimethyl-4H-benzo[d][1,3]oxathiine-1,1-dioxide 已被发现在区域选择性去质子化时与多种亲电子试剂反应,例如各种卤化物和醛。这该方法利用砜基团形成新的碳-碳键,同时充当掩蔽的羰基。随后的砜水解为许多有用的合成中间体提供了一种简便的方法。这种方法可以提供一种有用的替代二噻烷基团的方法。
