benzyl 2,3,6,7-tetrahydroazepine-1-carboxylate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 18 g m-chloroperbenzoic acid was added to 10 g benzyl 2,3,6,7-tetrahydro-1H-azepine-1-carboxylate in 250 ml dichloromethane at 0° C. in several portions. The mixture was allowed to warm to RT over 2 h. 1 L ethyl acetate was added and the solution was extracted with aqueous sodium bicarbonate, 1N aqueous sodium hydroxide and brine. The organic layer was evaporated and the residue was purified by chromatographie on silica gel (ethyl acetae/hexanes 1:5) to yield 10.4 g of the desired product. the solution was extracted with aqueous sodium bicarbonate, 1N aqueous sodium hydroxide and brine The organic layer was evaporated the residue was purified by chromatographie on silica gel (ethyl acetae/hexanes 1:5)

Conditions: temp:50.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 0.15 g Grubb's 2 catalyst was added to a solution of 8 g benzyl dibut-3-enylcarbamate in 680 mL toluene and heated at 50° C. for 5 h. The solvent was removed and the residue was purified by chromatographie on silica gel (ethyl acetate/hexane 1:5) to yield 6.6 g of the desired product. The solvent was removed the residue was purified by chromatographie on silica gel (ethyl acetate/hexane 1:5)
