Synthesis of functionalized tetrahydropyridazines via catalyst-free self [4 + 2] cycloaddition of in situ generated 1,2-diaza-1,3-dienes†
Abstract
An efficient method for the synthesis of structurally diverse functionalized tetrahydropyridazines via self [4 + 2] cycloaddition of in situ generated 1,2-diaza-1,3-dienes was developed, which may play an important role in drug discovery.
