Synthesis of 1′-substituted 4′,4′-dimethyl-6′-methoxy-4′H-spiro[cyclohexane-1,3′-isoquinolines]
摘要:
The reaction of 1-(4-methoxyphenyl)-1-(1-methylcyclohexyl)ethanol with nitriles in concentrated sulfuric acid afforded 1'-substituted 6'-methoxy-4',4'-dimethyl-4'H-spiro[cyclohexane-1,3'-isoquinolines] as a result of consecutive Wagner-Meerwein rearrangement and Ritter reaction.
