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.

A copper(II) acetate catalyzed ring-opening cross-coupling of cyclopropanol with sulfonyl azide has been developed. By this method, various β-amino ketones have been made efficiently in medium to high yields and venerable functional groups such as benzylic C–H, alkyl and aryl bromides, alkyl sulfonate, silyl ether and alkene are compatible with these reaction conditions. Control experiments have precluded

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
