Chen, Xiaoyu | Day, David Philip | Teo, Wan Teng | Chan, Philip Wai Hong
A synthetic method for the efficient assembly of bicyclo[2.2.1]hept-2-en-7-ones that relies on gold(I)-catalyzed Rautenstrauch rearrangement followed by Brønsted acid-mediated formal [3 + 2]-cycloaddition/deacetylation of 1,8-diynyl vinyl acetates at room temperature under atmospheric conditions is described.
