Diastereoselective synthesis of 1,10-dihydropyrrolo[1,2-a][1,10]phenanthroline derivatives via 1,3-dipolar cycloaddition reaction
The functionalized 1,10-dihydropyrrolo[1,2-a][1,10]phenanthroline derivatives were synthesized in good yields and with high diastereoselectivity by 1,3-dipolar cycloaddition reactions of N-phenacylphenanthrolinium bromides or N-ethoxycarbonylmethylene phenanthrolinium bromide with various nitrostyrenes in acetonitrile at room temperature in the presence of triethylamine.
