title: Parallel microwave-assisted library of imidazothiazol-3-ones and imidazothiazin-4-ones.
abstract: A methodology for the generation of a microwave-assisted parallel library and its conversion into a second library is described. A 24-membered library of substituted 4(5)-sulfanyl-1H-imidazoles was generated and subsequently converted into a second library of bicyclic imidazo[5,1-b]thiazol-3-ones and imidazo[5,1-b]thiazin-4-ones. The first library was generated using a three-component reaction and transformed into a daughter library with a polymer-supported coupling agent. The procedure involved the use of an array of expandable reaction vessels, which can accommodate pressure buildup due to microwave heating without loss of volatile solvents or reagents. Library generation time for each library was 16 min.
