摘要：

The syntheses, conformational and spectroscopic studies of N-borane adducts of 14 nitrogen containing six-membered ring heterocycles are reported. It was found that borane can act as a conformational and configurational locking agent. In addition, it can be very helpful for the assignment of the chemical shifts of other atoms or groups in the molecule as well as to ascertain the configuration at substituted carbons.
