An unusual synthesis and crystal interaction studies of a highly functionalised thiophene system
摘要:
Several novel functionalised thiophenes have been synthesised via an unusual acid catalysed reaction of S-acetyl fimbrolides. The crystal structure analysis of one of the thiophene products reveals interesting intermolecular hydrogen bonding and carbonyl-carbonyl (C=O center dot center dot center dot C=O) dipolar interactions.
