Pages 12292–12293. The names given for compounds 3–7 were incorrect. The correct IUPAC names are as follow:
3, 4-(Prop-2-yn-1-yloxy)phenol
4, (E)-Methyl 4-((2-hydroxy-5-(prop-2-yn-1-yloxy)phenyl)diazenyl)benzoate
5, (E)-4-((2-Hydroxy-5-(prop-2-yn-1-yloxy)phenyl)diazenyl)benzoic acid
6, (E)-2,5-Dioxopyrrolidin-1-yl-4-((2-hydroxy-5-(prop-2-yn-1-yloxy)phenyl)diazenyl)benzoate
7, (E)-4-((2-Hydroxy-5-(prop-2-yn-1-yloxy)phenyl)diazenyl)-N-(13-oxo-17-(2-oxohexahydro-1H-thieno[3,4-d]imidazol-4-yl)-3,6,9-trioxa-12-azaheptadecyl)benzamide (Alk-azo-biotin)
Supporting Information. In Scheme S2, the structures of the cleavable alkyne-biotin tags were incorrect. The revised Supporting Information file provided here shows the correct structures. Specifically, in the revised structures the correct propargyl ethers replace the incorrect structures with the arene directly substituted by propyne. The incorrect structures were initially characterized as being correct. However, upon further inspection, they are indeed the propargyl ethers shown in the corrected Scheme S2.
Mass spectral (MS) analyses of compounds 4, 5, and 7 are provided here in a new Supporting Information file, with the correct mass peaks highlighted.
