Cylindrocyclophane A (VIDEO) California Institute of Technology This video is under embargo. Please login to access this video. Caption A team of scientists led by Caltech and Emory University has synthesized a highly complex natural molecule, cylindrocyclophane A, using a novel strategy that functionalizes normally nonreactive bonds, called carbon–hydrogen (C–H) bonds. The work demonstrates a new category of reactions that organic chemists can consider as they work to create natural products that could be used in pharmaceuticals or new materials, or to produce organic chemicals in more sustainable ways.
