a solid support could be simply and efficiently prepared by reaction of the corresponding resin-bound acid chlorides with excess TMSdiazomethane, without any bases. These α-TMSdiazoketones were used via carbenes or carbenoids for a variety of solid-phase reactions. These useful solid-phase reactions allow efficient construction of diverse compound libraries by use of combinatorial chemistry, due to
