Bis(enaminones): Key INtermediates for novel α,ω- Bis(pyrazolylphenoxy), Bis(pyranylphenoxy), and Bis(benzo[b]furanylphenoxy) alkanes

Abstract

New bis(enaminone) derivatives, 5a,b and 9a,b, were prepared in good yields. Their synthetic utilities as key intermediates for the synthesis of novel bis(pyrazole) 12a,b, bis(pyrane) 17a,b, and bis(benzo[b]- furan) 20a-d derivatives were also investigated.© 2009 HeteroCorporation.
