ENAMINONES AS BUILDING BLOCKS IN ORGANIC SYNTHESIS: SYNTHESIS OF NEW POLYFUNCTIONAL PYRIDINES,CONDENSED PYRIDINES,AND PENTA SUBSTITUTED BENZENE

ABSTRACT

Several new thienopyridine and methylthioether derivatives have been synthesized. New synthesis of pyrido2,3-b]-thieno3,2-d]pyrimidine and penta substituted benzene were achieved.
