Perhaps the most exotic and unexpected among them is the emergence of chirality (i.e., handedness) in polar vortices and skyrmions that arise from a sequence of achiral materials (20, 23). WebOct 30, 2024 · (E)-Cyclooctene was the first chiral olefin synthesized, 22 but the strong dependence of the stereochemical stability on the ring size of the (E)-cycloalkene has precluded their occurrence. The main limiting factor for the development of this area of research is the shortage of general and efficient synthetic routes to enantiopure …
