Alkyl β-oxoalkanesulfonates: Synthesis and structure of methyl aroylmethanesulfonates
摘要:
A number of new methyl esters of para-substituted benzoylmethanesulfonic acids was synthesized. An ability of both esters and salts to tautomeric transformations was examined. The esters were found to undergo an acid cleavage in alkaline medium.
A series of optically active β-hydroxy sulfonamides were synthesized for the first time by asymmetric transfer hydrogenation of the corresponding β-ketosulfonamides using the Ru–TsDPEN–HCOOH–Et3N catalytic system, in excellent yields (up to 95%) with excellent diastereo- (up to > 99:1 dr) and enantioselectivities (up to >99% ee).
