CAN-mediated oxidative cleavage of 4-aryl-3,4-dihydroxypiperidines
摘要:
A CAN-mediated oxidative cleavage of 4-aryl-3,4-dihydroxypiperidines 2Aa-Be to P-amino carbonyl compounds 3Aa-Be and 4Aa-Be in different ratios is described. This facile strategy was also used to synthesize racemic fluoxetine (5). (c) 2006 Elsevier Ltd. All rights reserved.

Fe(OTf)3-catalyzed synthesis of acyclic β-aminoketones from 3-aryl propargyl alcohols and nitrogen nucleophiles were investigated. Results showed that propargyl alcohols without bulky groups α to the hydroxyl group underwent the transformation smoothly. Sulphonamides exhibited the higher reactivity than amides as the nitrogen nucleophiles and the transformation of acyclic β-aminoketones were finished
