Synthesis of 3-Hydroxy-4,5-dimethyl-2(5H)-furanone and its analogues; utilisation of an intramolecular darzens reaction
摘要:
The intramolecular Darzens reaction of chloroacetates of hydroxy ketones leads to alpha, beta-epoxy-gamma- and delta-lactones. Acid catalysed rearrangement of the latter furnished the alpha-keto lactones 1, 10, 16 and 20.
