    peri-Naphthylenediamines. 38. Naphthalene and acenaphthene “proton sponges” with +M substituents in ortho positions with respect to peri-dimethylamino groups
    摘要:
    Previously unknown 4,5,6,7-tetrakis(dimethylamino)acenaphthene, which is the first acenaphthene derivative containing four vicinal dialkylamino groups, was synthesized based on 5,6-bis(dimethylamino)-4,7-dinitroacenaphthene. The total synthesis of 1,2,7,8-tetrakis(dimethylamino) naphthalene was carried out starting from 3,6-dinitronaphthalic anhydride. Other "proton sponges" of this type, viz., 1,7,8-tris((dimethylamino)-2-methoxy- and 1, 8 -bis(dimethylamino)-2,7-dipiperidinonaphthalenes, were prepared by the nucleophilic substitution in 2,7-dimethoxy-1,8-dinitronaphthalene. In solutions, 1,2,7,8-tetrakis(dimethylamino)naphthalene and its analogs can form di- and trications in the presence of acids. The basicity constants pK(a)(1) of the compounds measured in DMSO depend in a complex way on their structures but correlate with the basicity index B, which is determined by changes in the Chemical Shifts 811 after the addition of the first proton. Due to low C-nucleophilicity of ortho-disubstituted "proton sponges" in combination with high basicity, these compounds hold considerable promise as reagents in organic synthesis.

The procedure allows the combination of a reduction (catalytic or by tin dichloride in acidic media) and a methylation in a one-pot process. (© Wiley-VCH Verlag GmbH & Co.

    The primary kinetic isotope effect (kH/kD) for proton transfer from protonated 1,8-bis(dimethylamino)-2,7-dimethoxynaphthalene to bases has a value of unity even for reactions for which the proton donor and acceptor have similar pK values, a condition which would have been expected to lead to a maximum isotope effect.

    The lithiation of 2,7-disubstituted derivatives of 1,8-bis(dimethylamino)naphthalene (DMAN, proton sponge) bearing potentially ortho-directing OMe, NMe2, and SMe groups was studied. It has been shown that OMe groups facilitate selective dual β-lithiation of the naphthalene moiety while the 2(7)-NMe2 groups allow only monolithiation presumably due to the decreased acidity of the ring C–H bonds and conformational
