Abstract

A range of compounds containing two 3-oxygenated thiophene rings linked through the oxygen atoms by a variety of alkyl and heteroalkyl chains has been prepared and subjected to electrophillic substitution, at C (2) and C (2′), giving,, bis-Mannich bases containing 14- to 22-membered rings; preliminary X-ray diffract
