    Synthesis of 2-sulphur-substituted 1,4-anthraquinones. Application to the Synthesis of Anthracyclinone Precursors
    摘要:
    2-sulphur-substituted 1,4-anthraquinones 8a,b and 10 have been prepared by annelation reactions of the anions of furanones 5a,b with naphthoquinone monoketals of type 6 and 9. Diels-Alder reaction of the 1,4-anthraquinones 11a,b with (E)-1,3-bis(trimethylsilyloxy)buta-1,3-diene (12) affords ABCD tetracyclic systems related to those existing in anthracyclinones.

    afford exclusively the C-5 substituted Michael adducts in good yield. The annelation reactions of the anions generated from furanones 30 and 33 with naphthoquinone monoketals 11 and 12 lead to 2-sulphur-substituted 1,4-anthraquinones 32, 35 and 36. Diels-Alder reaction of the 1,4-anthraquinones 41 and 42 with (E)-1,3-bis[(trimethylsilyl)oxy]buta-1,3-diene (37) affords ABCD tetracyclic systems related

    The behavior of the furanones 1–4 towards nitrile oxides 5–7 has been investigated, in particular with respect to the regio- and stereoselectivity. Cycloaddition of benzonitrile oxide (5) to 4,5-diethylsulphonylfuran-2(5H)-one (12) leads as sole addition product to the isoxazoline 30, that was easily aromatized to the isoxazole derivative 31, which is a useful synthon for the preparation of heteroanthracyclinone
