Abstract: Abstract A new unexpected hybrid based on the arylidene-thiazolidinone and 1,3,4-thiadiazole scaffolds via combined S-alkylation and Smiles rearrangement dual protocols. The one-pot reaction of arylidene-thiazolidinone with the hydrazonoyl chloride in a basic medium (Et3N) with…

Abstract: We have achieved a facile access to N-(2-halophenyl)-2-hydroxyphenylimine derivatives via imine anion-mediated Smiles rearrangement. When 2-(2-halophenoxy)benzonitriles were treated with 1.2-1.4 equiv of organolithium reagents, nucleophilic addition to the nitrile group followed by Smiles rearrangement occurred…

Abstract: This study reports two synthetic approaches leading to 2-aminobenzoxazoles and their N-substituted analogues. Our first synthetic strategy involves a reaction between various o-aminophenols and N-cyano-N-phenyl-p-toluenesulfonamide as a nonhazardous electrophilic cyanating agent in the presence of…

Abstract: A nitrogen-oxygen Smiles rearrangement was reported to occur after collisional activation of the PhN(R)CH2CH2O- (R = alkyl) anion, which undergoes a five-membered ring rearrangement to form a phenoxide ion C6H5O-. When R = H, such…

Abstract: A decarboxylative, desulfonylative Smiles rearrangement is presented that employs activated-ester/energy transfer catalysis to decarboxylate β-amino acid derived starting materials at room-temperature under visible light irradiation. The radical Smiles rearrangement gives a range of biologically active…
