Abstract: We report the first crystallization-induced diastereomer transformations (CIDTs) of donor-acceptor (D-A) cyclopropanes, providing access to important chiral nonracemic building blocks for stereospecific and stereoselective transformations. Lewis acids rapidly epimerize aniline-substituted D-A cyclopropanes through reversible C-C… read more here.
