Synthesis of 14-Aryl-13-oxadispiro[3.1.5.3]tetradecane-5,12-diones by the reformatsky reaction
摘要:
Methyl 1-bromocyclohexanecarboxylate reacts with zinc in the presence of cyclobutanecarbonyl chloride to give methyl 1-(cyclobutylcarbonyl)cyclohexanecarboxylate. Bromination of the latter leads to the formation of methyl 1-(1-bromocyclobutylcarbonyl)cyclohexanecarboxylate which reacts with zinc and aromatic aldehydes, yielding 14-aryl-13-oxadispiro[3.1.5.3]tetradecane-5,12-diones.
