Published in 2021 at "Journal of Molecular Structure"

DOI: 10.1016/j.molstruc.2021.130156

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… read more here.

Published in 2022 at "Organic letters"

DOI: 10.1021/acs.orglett.2c01349

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… read more here.

Published in 2019 at "Organic letters"

DOI: 10.1021/acs.orglett.9b01848

Abstract: Asymmetric assembly of atropisomeric anilines from abundant and readily available precursors is one of the most challenging but valuable processes in organic synthesis. The use of highly efficient Smiles rearrangement to accomplish switchable enantioselective amination… read more here.

Published in 2019 at "ACS Omega"

DOI: 10.1021/acsomega.9b02702

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… read more here.

Published in 2022 at "Journal of the American Society for Mass Spectrometry"

DOI: 10.1021/jasms.2c00210

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… read more here.

Published in 2020 at "Chemical communications"

DOI: 10.1039/d0cc05049k

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… read more here.
