Synthesis of Indole-Dihydroisoquinoline Sulfonyl Ureas via Three-Component Reactions
indoles in a 3-component reaction to generate a library of dihydroisoquinoline derivatives. Using a differential protecting group strategy, products could be further derivatised. Synthesis of isoquinoline starting materials using several different methods is also described. Isoquinolines activated with sulfamoyl chlorides were reacted with indoles in a 3-component reaction to generate a library of
