Conformational control in the 3,7-diazbicyclo[3.3.1]nonane system
Abstract
The twin-chair or boat-chair conformation of 3,7-diazabicyclo[3.3.1]nonaes can be selected by forming N,N′-derivatives in which the N atoms have planer or pyramidal bonding patterns, respectively, e.g. acyl substituents for the former and arylsulphonyl or alkyl for the latter.
