    • BiocatalyticProduction of Chiral Benzotriazoles Employing Conventional Heating and Microwave Radiation 

      Meirelles, Matheus A.; Jeller, Alex H.; Ferreira, Irlon M.; Raminelli, Cristiano [UNIFESP]; Faria, Raquel S.; Silveira-Lacerda, Elisangela de Paula; Porto, Andre L. M. (Bentham Science Publ Ltd, 2017)
      Background: This paper describes the synthesis of chiral 1,2,3-benzotriazoles by the enzymatic kinetic resolution of beta-azidoalcohols using lipase from Candida antarctica B followed by a [3+ 2] cycloaddition reaction ...

    • Chemoenzymatic resolution of β-azidophenylethanols by candida antarctica and their application for the synthesis of chiral benzotriazoles 

      Rocha, Lenilson Coutinho; Rosset, Isac George; Melgar, Gliseida Zelayaran; Raminelli, Cristiano [UNIFESP]; Porto, André Luiz Meleiro; Jeller, Alex Haroldo (Sociedade Brasileira de Química, 2013-09-01)
      The kinetic resolutions of (±)-β-azidophenylethanols were carried out using lipase from Candida antarctica, and enantiomerically enriched (R)-β-azidophenylethanols and their corresponding (S)-β-azidophenylethyl acetates ...

    • Chemoenzymatic synthesis of organoselenium(IV) compounds and their evaluation as cysteine protease inhibitors 

      Piovan, Leandro; Alves, Marcio Fernando [UNIFESP]; Juliano, Luiz [UNIFESP]; Brömme, Dieter; Cunha, Rodrigo Luiz Oliveira Rodrigues [UNIFESP]; Andrade, Leandro H (Sociedade Brasileira de Química, 2010-01-01)
      A series of organoselenium dihalides (organoselenanes) was synthesized from organoselenides using a chemoenzymatic approach. The organoselenanes have variations in their stereochemistry and in the halogen atom bonded to ...
