    derivatives 4a–f and DDHQ esters 5a–f (- isomer 6a–f, - isomer 7a–f). While the aryl substituted spirokeone 17a gave a 2:1 mixture of 19a and the corresponding - isomer, the aryl substituted spiroketones 17b–d gave exclusively - isomers 19b–d. Heating acid chloride of acid 9c with DDHQ resulted in compounds 4a and 7a, thus confirming the structures assigned. Mechanism of formation of these compounds
    用干苯中的DDQ氧化螺酮3a-f,得到托克酮衍生物4a-f和DDHQ酯5a-f(-异构体6a-f,-异构体7a-f)。而芳基取代spirokeone 17A给予了2:1混合物19A相应的和-异构体,所述芳基取代的spiroketones 17B-d仅仅得到-异构体19B-d 。用DDHQ加热酸9c的酰氯得到化合物4a和7a,从而确认分配的结构。这些化合物的形成机理已经合理化。对化合物7d的2D 1 H- 1 H COSY,1 H- 13 C COSY,HMBC和2D NOESY的详细研究导致1 H和13 C NMR信号及其溶液构象的完全分配。

    the structures were finally confirmed by an X-ray crystal structure analysis of (12a). Hydrogenation of compounds (12a) and (13a) has been shown to give the dihydroxy compound (14) via C–C bond cleavage. An alternative synthesis of the dispironaphthalenones (12a) and (13a) was achieved by oxidation of the dihydroxy compound (14), prepared by an independent method. The generality of the oxidation of

    Spironaphthalenones 1b–g on reaction with hydroxylamine hydrochloride gave the expected pyrrolotropones 2b–g. Furanotropone 6, postulated as an intermediate in the formation of pyrrolotropones, remained unchanged on reaction with hydroxylamine hydrochloride in ethanol. Reaction of unsymmetrical spironaphthalenones 1h–o with NH2OH.HCl gave the rearranged pyrrolotropones 2h–o.
    与盐酸羟胺反应时,螺萘二酮1b–g得到预期的吡咯烷酮2b–g。呋喃酮6被假定为吡咯烷酮形成的中间体,在乙醇中与盐酸羟胺反应时保持不变。非对称螺萘醌1h-o与NH 2 OH.HCl的反应产生了重排的吡咯烷酮2h-o。

    Oxidation of bisnaphthols (1a-c) with DDQ resulted in the formation of 10a-a″, 10b-b″, 14a-c and 19a-c in addition to earlier reported products. Structures were assigned on the basis of detailed spectral analyses(1H, 13C, 1H1H HOMOCOSY and FUCOUP). Structures 10b, and 14c and 19a were further confirmed by single crystal X-ray analyses. The formation of these compounds has been explained by a suitable
