Sulfonated porous carbon catalyzed direct and efficient conversion of tertiary, allylic, and benzylic alcohols to thioesters
摘要:
A one-pot conversion of alcohols to thioesters using a sulfonated porous carbon (SPC) as a solid acid catalyst is reported. It was found that, when a tertiary, benzylic, or allylic alcohol was reacted with thioamides in the presence of SPC, the corresponding thioesters were produced in good to excellent yields in a short time.
A one-stepconversion of alcohols into thioesters under solvent-free conditions is reported. The alcohols were reacted with primary thioamides in the presence of p-toluenesulfonic acid under solvent-free conditions to produce the corresponding thioesters in good to excellent yields.
nickel-catalyzed C–C bond cleavage of thioesters with sp2-hybridized electrophiles. Aryl bromides, iodides, and alkenyl triflates can participate in thioester transfer reaction of aryl thioesters, affording a wide range of structurally diverse new thioesters in yields of up to 98% under mild reaction conditions. With this protocol, it is possible to construct alkenyl thioesters from the corresponding ketones
