, (2008/06/13)
Novel solid supported intermediate products of the general formula coupled to a solid polymeric support through one or both of the R1 groups or through the R4 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.

The pyridine and quinoline derivatives 2, 3, and 6 with an activated methylene group at α-position in respect to the ring nitrogen atom were converted with 1, 8, or 9 into fused pyridopyridine derivatives 4, 5, 7, and 10.In an analogous manner were the aminopyridines 16 and 17 transformed with thiazolone 9 into pyridopyrimidine derivatives 20, 21, 25, and 26.
