Intermediate products, methods for their preparation and use thereof

摘要

Novel solid supported intermediate products of the general formula coupled to a solid polymeric support through one or both of the R<1 >groups or through the R<4 >group which are suitable for synthesis of heterocyclic compounds are disclosed. Methods for preparing such intermediate products are also disclosed and also the use of the intermediate products in simple and fast methods on solid phase for synthesis of heterocycles.
