✦ Synopsis

The NW? spectra of compounds l-5, recorded at different temperatures, are discussed and interpreted in terms of conformational eguilibrium. Ground state conformations are found to be chiral, ring inversion barriers are surprisingly high (ca 48 kJ/mol).

An investigation of the molecular dynamics of substituted 1,3,4,5-tetrahydro-2H-l,Ibenzodiazepin-2-0ne derivatives revealed that these molecules adopt cycloheptadiene-like boat conformations. There is an equilibrium between the quasi-axial and the quasiequatorial conformer in which the quasi-axial c
