Abstract
The preprogrammed achiral oligomers (3) and (4), composed of pyridine-pyrim idine sequences containing up to 27 heterocycles, undergo self-organization into extended multiturn helical structures both in solution and in the sol id state, with spontaneous chiral resolution of 3 on crystallization.
