	Abstract	Naphthoquinones, Stypandrone. D ianellinone, Phenol O xidation The naphthoquinone stypandrone (2b) ist synthesized via the interm ediates 5 a , 6a and 6b. Selective monoalkylation of its hydroquinone yields the m onoether 12b, which, on phenol oxida tion and oxidative dealkylation, leads to 13 and dianellinone (2a). The synthesis confirms the 3.3'-dim erisation of the natural product.

	Title	Structural Studies on Vindolinine
	Abstract	Catharanthus roseus. A pocynaceae. 19-S-V indolinine, 19-R-V indolinine. NM R Spectra 19-S-Vindolinine has been found to undergo an interesting isom erisation in chloroform to 19-R-vindolinine at room tem perature. N O E D S m easurem ents have been carried out on both isom ers and a I3C solid state CP-M A S spectrum recorded for 19-S-vindolinine. The structure assigned as 16-epi-19-S-vindolinine to an alkaloid isolated previously from Catharanthus roseus has been revised in the light of corrected l3C NM R values for 19-S-and 19-R-vindolinine.

By interaction with a solution o f PPh4Cl in C H 2C12 this product can be converted into PPh4[M oCl4(N 3S2)], from which [M oCl3(N 3S2) ] 2 can be obtained by reaction with gallium trichloride. The crystal structure o f PPh4 [M oCl4(N 3S2)] was determ ined by X-ray diffrac tion (2436 observed reflexions, R = 0.047). Crystal data: orthorhom bic, space group Pbca, Z = 8 , a = 1384.3, b = 2092.4, c = 1898.6 pm. The structure consists o f PPh4+ cations and [M oC l4(N 3 S2)]~ anions in which the Mo atom s are part o f a planar M oN 3S2 ring with M oN bond lengths o f 183 and 184 pm and nearly equal NS bond lengths (m ean value 158 pm). The PPh4® ions are arranged in centrosymmetric (PPh4®) 2 pairs in a manner that normally is encountered with doubly charged anions. The structure found for PPh4 [M oCl4(N 3S2)j differs from the known m onoclinic structures o f A sPh4[M oCl4(N 3S2)] and A sPh4[WCl4(N 3S2)]; an analysis o f their pack ing show ed that they form layers o f AsPh4® ions in which three phenyl groups o f every A sP h4® ion are adjacent to phenyl groups of four other A sPh4® ions.

The reaction is first ord er in [Pb(IV)] and second order in [Ester], and is catalysed by pyridine and 2,6-lutidine. The pyridine catalysed reaction is first order each in [Pb(IV)]. [Ester] and [Pyridine]. A kinetic isotope effect is observed in oxidation of methyl m andelate for both uncatalysed reaction (kH/kD = 4.2) and pyridine catalysed reaction (kH/kD = 1.8). Activation param eters for both uncatalysed and pyridine catalysed reactions are evaluated. The results are in accord with Linear Free Energy Relationship (L .F . E .R .) and the reaction constant (o = +0.75) obtained supports proton transfer in the a -C —H bond rupture in in catalysis, as a ligand or as a base is discussed.
