반응 단계
Commercially available 2-nitrocyclohexanone was refluxed in MeOH in presence of Amberlyst A21 to give 6-nitrohexanoic acid methyl ester 1. Reaction of 1 with N,N′-dibenzylethylenediamine diacetate and paraformaldehyde gave diazepine 2 which was firstly hydrogenated to 3 and then alkylated with t-butyl bromoacetate to give pentaester 4. Selective hydrolysis of 4 by means of LiOH in THF/H2O gave 5. Overall yield 13%.
