โœฆ Synopsis


Mild and efficient preparation of acid-labile resins with displaceable halide linkers (3 and 4, X = Br and 1) is described. These resins can be used in combinatorial organic synthesis of numerous drug-scaffold libraries, Their synthetic utility is exemplified by high yielding N-alkylations with structurally and electronically diverse sets of aliphatic and aromatic amines. Amongst the various resins modified and evaluated in this study, Wang resin derived bromo resin (3, X = Br) offers the best practical choice with respect to loading, stability, and chemical reactivity.

Abstractรa-TMSdiazoketones on a solid support could be simply and efยฎciently prepared by reaction of the corresponding resin-bound acid chlorides with excess TMSdiazomethane, without any bases. These a-TMSdiazoketones were used via carbenes or carbenoids for a variety of solid-phase reactions. These
