W.Tetrahedron Lett.1992,34, 987) have led to the questioning of all structures established by thiolytic methods (Balas, L.; Vercauteren, J.Magn. Reson. Chem.1994,32, 386). The latter authors go far beyond the conclusions of the former, who solely reject thequantitativeinterpretation ofexhaustivethiolysis experiments. The \u201csequencing\u201d of condensed tannins takes place under the milder conditions ofpartialthiolysis. There is at present no indication that the reported side reaction occurs to any significant extent under these conditions. Furthermore, even if this reaction takes place and the sequence of events postulated by McGraw et al. is entirely reversible, and therefore re-addition of the substituted phloroglucinol fragment could initiate a return of the reactants to either a 4,6- or 4,8-linked 4-(benzylthio)oligomer, steric factors would favor the former over the latter. The finding of 4,8-linkage in the case of compounds11and12(ref 6) leaves thus no doubt that it is genuine. Furthermore, as no 4,6-linked fragments are formed from these compounds, the finding of 4,6-linkage in other cases should be considered genuine as well. Finally, if re-addition of the substituted phloroglucinol fragment did actually occur, so would the addition of any nonhindered phenolic hydroxyl group of other components present in the reaction mixture, resulting in a complex mixture of products rather than just the isomerized 4-(benzylthio)oligomer. It is, of course, assumed that all major fragments, rather than just a few arbitrarily selected components of complex mixtures, have been identified in these experiments."},{"key":"jo020393fb00019\/jo020393fb00019_1","first-page":"1209","author":"Pinus","year":"1982","journal-title":"J.
