✦ Synopsis
Five-dimensional libraries of dipeptide amides are readily prepared using a solid-phase tandem Petasis-Ugi multi-component condensation protocol on either a RINK amine or Universal RINK isonitrile resin. The method is practical and can be automated to prepare a large number of compounds useful for high throughput biological screening.
