    • In this review we use the syn/anti nomenclature according to the Masamune convention (see S. Masamune, S. A. Ali, D. L. Snitman, D. S. Garvey, Angew. Chem. Int. Ed. Engl. 1980, 19, 557-558 and S. Masamune, T. Kaiho, D. S. Garvey, J. Am. Chem. Soc. 1982, 104, 5521-5523, that is, considering the amino and nitro functionalities as the substituents of the carbon chain oriented in a zigzag disposition. Other dispositions, used in some cases in the original publications cited here, lead to misunderstanding of the relative configuration and should be avoided. Diastereoselectivities are indicated as diastereomeric ratios in the form of dr, as recommended for stereoselective reactions in which at least two isomers can be obtained. For an excellent and comprehensive discussion on the terminology used in stereochemistry see: G. Helmchen, in Stereoselective Synthesis, Houben-Weyl Eds, G. Helmchen, R. W. Hoffmann, J. Mulzer, E. Schau

    • According to the experimental results and ESI-HRMS and 1H NMR studies of 36-CuI, the authors speculated that complex A should be the active species. For more details of discussion and the proposed transition state model, see the Supporting Information of the original publication 9 (ref. 35).
