On March 18, 2015, Goodman, C. Guy; Walker, Morgan M.; Johnson, Jeffrey S. published an article.Safety of (R)-5-Benzyl-2-mesityl-6,7-dihydro-5H-pyrrolo[2,1-c][1,2,4]triazol-2-ium tetrafluoroborate The title of the article was Enantioconvergent Synthesis of Functionalized γ-Butyrolactones via (3 + 2)-Annulation [Erratum to document cited in CA162:137454]. And the article contained the following:
Some of the catalyst identifiers (A-G) used in the Supporting Information did not match those shown in the paper; the Supporting Information has been updated. The authors were made aware of several relevant publication involving enantioconvergent proline-catalyzed aldol reactions of chiral racemic electrophiles and provide the relevant citation information. The experimental process involved the reaction of (R)-5-Benzyl-2-mesityl-6,7-dihydro-5H-pyrrolo[2,1-c][1,2,4]triazol-2-ium tetrafluoroborate(cas: 1469801-67-9).Safety of (R)-5-Benzyl-2-mesityl-6,7-dihydro-5H-pyrrolo[2,1-c][1,2,4]triazol-2-ium tetrafluoroborate
