New General Sulfinylating Process for Asymmetric Synthesis of Enantiopure Sulfinates and Sulfoxides
摘要:
[GRAPHICS]A general process for the efficient synthesis of sulfinyl transfer agents has been developed using cinchona alkaloids quinine and quinidine as chiral auxiliaries. The importance of these new and unique sulfinyl transfer agents is exemplified by the expedient synthesis of several sulfoxides in excellent enantiopurities and high yields.
