Mohamed RK, Mondal S, Jorner K, Delgado TF, Lobodin VV, Ottosson H, Alabugin IV.
PMID: 26536479
J Am Chem Soc. 2015 Dec 16;137(49):15441-50. doi: 10.1021/jacs.5b07448. Epub 2015 Dec 03.

The last missing example of the four archetypical cycloaromatizations of enediynes and enynes was discovered by combining a twisted alkene excited state with a new self-terminating path for intramolecular conversion of diradicals into closed-shell products. Photoexcitation of aromatic enynes...
