1,5-Dibenzyl-3-propargyl-1,5-benzo­diazepine-2,4-dione

The title compound, C26H22N2O2, features a benzene ring fused with a seven-membered diazepine ring; the latter ring adopts a boat conformation (with the propargylallyl-bearing C atom as the prow and the fused-ring C atoms as the stern). The phenyl ring of one of the two benzyl substituents is disordered over two positions in a 0.812 (11):0.188 (11) ratio

1,5-Dimethyl-3-propargyl-1H-1,5-benzodiazepine-2,4(3H,5H)-dione

The asymmetric unit of the title compound, C14H14N2O2, comprises two independent mol­ecules, which slightly differ in the orientation of the propargyl chain. In both molecules, the diazepine ring adopts a boat conformation with the propargyl-bearing C atom as the prow and the C atoms at the ring junction as the stern. The carbonyl O atom of one independent mol­ecule is hydrogen bonded to the acetyl­enic H atom of the other independent mol­ecule. In the crystal, symmetry-related mol­ecules are linked together by C—H⋯O hydrogen bonds, forming a ribbon-like structure along the c axis

4-[(1,5-Dibenzyl-2,4-dioxo-2,3,4,5-tetra­hydro-1H-1,5-benzodiazepin-3-yl)meth­yl]-1-n-octyl-1H-1,2,3-triazole

The reaction of 1,5-dibenzyl-3-propargyl-1,5-benzodiazepine-2,4-dione with 1-azido-n-octane in the presence of catalysts leads to the formation of the title compound, C34H39N5O2, which features a phenyl­ene ring fused with a seven-membered diazepinyl ring. The latter ring adopts a boat conformation with the octyltriazolylmethyl-bearing C atom as the prow and the fused-ring C atoms as the stern. The octyltriazolylmethyl substituent occupies an axial position

1-(12-Azido-n-dodec­yl)-4-[(1,5-dibenzyl-2,4-dioxo-2,3,4,5-tetra­hydro-1H-1,5-benzodiazepin-3-yl)meth­yl]-1H-1,2,3-triazole

The reaction of 1,5-dibenzyl-3-propargyl-1,5-benzodiazepine-2,4-dione with 1,12-diazido-n-dodecane in the presence of catalysts leads to the formation of the title compound, C38H46N8O2. The seven-membered diazepinyl ring adopts a boat conformation with the azido­dodecyl­triazolylmethyl-bearing C atom as the prow and the fused-ring C atoms as the stern. The octyltriazolylmethyl substituent occupies an axial position
