(Microwave-assisted Combinatorial Synthesis) for generating combinatorial libraries is described. The technology is applied to the high throughput, automated, one-step, parallel synthesis of diverse substituted pyridines using the Hantzsch synthesis. The advantages of microwave-assisted chemistry for combinatorial synthesis include a broad range of available chemistries, simple reaction setup and product
