Mary’s paper on (4+3) cycloadditions has been published in J. Comp. Chem.! As our group knows had very little previous knowledge about (4+3) cycloadditions, we were very happy to have our colleague, Prof. Michael Harmata, guide us in performing these calculations. The study can be found here: http://dx.doi.org/10.1002/jcc.70412 .
