摘要
This communication reveals the synthesis and application of a novel resin bound isonitrile. The resin is an example of a novel safety-catch linker which upon BOG-activation can be resin cleaved with a variety of nucleophiles. Use of this polymer supported isonitrile in the Ugi multi-component reaction (MCR), followed by resin clipping and cyclization allows access to diverse arrays of 1,4-benzodiazepine-2,5-diones, diketopiperazines and ketopiperazines respectively. The methoxide safety-catch clipping strategy and subsequent solution phase cyclization offers similar advantages to a traceless linker. (C) 1998 Elsevier Science Ltd. All rights reserved.
