1,5-Dibenzyl-3-propargyl-1,5-benzo-diazepine-2,4-dione.

The title compound, C(26)H(22)N(2)O(2), 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.

3-Allyl-1,5-dibenzyl-1,5-benzodiazepine-2,4-dione.

The title compound, C(26)H(24)N(2)O(2), features a benzene ring fused with a seven-membered diazepine ring; the latter ring adopts a boat conformation (with the allyl-dimethyl-amino-methyl-bearing C atom as the prow and the fused-ring C atoms as the stern).

Ethyl 2-{4-[(1,5-dibenzyl-2,4-dioxo-2,3,4,5-tetra-hydro-1H-1,5-benzo-diazepin-3-yl)meth-yl]-1H-1,2,3-triazol-1-yl}acetate.

The reaction of 1,5-dibenzyl-3-propargyl-1,5-benzodiazepine-2,4-dione with ethyl azido-acetate in the presence of copper sulfate pentahydrate and sodium ascorbate leads to the formation of the title regioisomer, C(30)H(29)N(5)O(4), which features a phenyl-ene ring fused with a seven-membered diazepinyl ring. The latter ring adopts a boat conformation (with the methyl-triazolylacetate-bearing C atom as the prow and the fused-ring C atoms as the stern). The benzyl groups connected to the diazepinyl ring jprotrude from the sides; the methyl-triazolylacetate substituent occupies an axial position.

4-[(1,5-Dibenzyl-2,4-dioxo-2,3,4,5-tetra-hydro-1H-1,5-benzodiazepin-3-yl)meth-yl]-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, C(34)H(39)N(5)O(2), which features a phenyl-ene 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-dodec-yl)-4-[(1,5-dibenzyl-2,4-dioxo-2,3,4,5-tetra-hydro-1H-1,5-benzodiazepin-3-yl)meth-yl]-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, C(38)H(46)N(8)O(2). The seven-membered diazepinyl ring adopts a boat conformation with the azido-dodecyl-triazolylmethyl-bearing C atom as the prow and the fused-ring C atoms as the stern. The octyltriazolylmethyl substituent occupies an axial position.
