Ethyl 2-{4-[(1,5-dibenzyl-2,4-dioxo-2,3,4,5-tetra­hydro-1H-1,5-benzo­diazepin-3-yl)meth­yl]-1H-1,2,3-triazol-1-yl}acetate

Abstract

The reaction of 1,5-dibenzyl-3-propargyl-1,5-benzodiazepine-2,4-dione with ethyl azido­acetate in the presence of copper sulfate pentahydrate and sodium ascorbate leads to the formation of the title regioisomer, C₃₀H₂₉N₅O₄, which features a phenyl­ene ring fused with a seven-membered diazepinyl ring. The latter ring adopts a boat conformation (with the methyl­triazolylacetate-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 methyl­triazolylacetate substituent occupies an axial position.

Experimental

To a solution 1,5-dibenzyl-1,5-benzodiazepine-2,4-dione (1 mmol) t-butyl alcohol/water (1/2, 8 ml) was added copper sulfate pentahydrate (1 mmol), sodium ascorbate (2 mmol) and ethyl azidoacetate (5 mmol). Stirring was continued for 8 h. The solution was diluted with water (20 ml) and the organic compound extracted with ethyl acetate (2 x 20 ml). The extracts were washed with brine and dried over sodium sulfate. The compound was recrystallized from ether to give colorless crystals.

Refinement

Carbon-bound H-atoms were placed in calculated positions (C—H 0.94 to 0.98 Å) and were included in the refinement in the riding model approximation, with U(H) set to 1.2–1.5U(C).

The carbon-carbon distance in the ethyl end of the molecule was tightly restrained to 1.540±0.005 Å. Attempts to model this unit as being disordered over two sites required a large number of restraints.
