“Cyclopropanation of Cyclopropanes”: GaCl₃-Mediated Ionic Cyclopropanation of Donor–Acceptor Cyclopropanes with Diazo Esters as a Route to Tetrasubstituted Activated Cyclopropanes

The Journal of Organic Chemistry, 2021
A new ionic cyclopropanation process involving the addition of diazo esters to donor-acceptor cyclopropanes (DAC) activated by GaCl3 has been developed. The reactions occur via 1,2-zwitterionic gallium complexes with elimination of nitrogen in all cases to give 1,1,2,3-tetrasubstituted cyclopropanes as the main products.

Cyclopropane-pituitrin Incompatibility

Anesthesiology, 1944
Abstract It is surprising to note the paucity of cases of pituitrin shock, especially of those with fatal result, reported in the literature. It is probable that the condition is not as rare as this would indicate, but its occurrence should be kept in mind.
