Finally, various -coordinated furan complexes of pentaamineosmium(n) were converted, in a similar way, to the corresponding iminium salt of 2-[l-(iV-methylimino)ethyl]furan-Os complexes.372... 

Initially, kinetic resolutions of 2-(trimethylsilyl)-5-[l -(2, 2, 2 -trifluoro-l -hydroxy-ethyl)]furan with a wide variety of lipases and vinyl alkanoates were examined in 1,2-dichloroethane. On the basis of these results, the system consisting of an enzyme (Novozym 435, Candida antarctica, Novo Nordisk Co. Ltd.) and vinyl propionate was sufficient to obtain optical pure alcohol and ester with a high -value. Moderate effect on the optical purity was observed on changing the organic solvents. Obviously, Novozym 435-CH2ClCH2Cl system is the most convenient practical system for obtaining the optically pure alcohol and the ester on the basis of comparison of the reaction time and the -value. 

As a consequence of bottle aging, carbohydrate conversions can occur, although slowly at cellar temperature, to form the caramel-like 2-furfural aroma for example, in aged Madeira wines. Rapp and Giintert (86MI141) have shown that such carbohydrate decomposition in Riesling wines leads to 2-furfural 9,2-acetylfuran 10, ethyl furan-2-carboxylate 11, 2-formyl pyrrole 12, and 5-hydroxymethylfurfural 13.

Similar results were obtained with TpRu(Me)(CO)(NCMe) and furan yielding, catalytically, 2-ethyl furan [Eq. (3)] and thiophene yielding 2-ethyl thiophene.

Nitriles can be used as starting material for the bisdithioesters (62 n = 4, 5, lO), whereas the derivatives with shorter chain lengths (62 n = l-3), as well as methyl dithiocinnamate (63), are accessible from /VA -disubstituted thioamides via the corresponding imidothioate iodides. Methyl di-thioacrylate (65), the simplest unsaturated dithioester, was prepared by flash vacuum thermolysis of a precursor dithioester (64), which had been obtained from the corresponding nitrile (equation 64). It can be isolated as a red monomeric compound at 77 K but dimerizes rapidly at room temperature. The p,7-unsaturated isoprene derivative (66) and the methyl 2-arylpropanedithioates (67) were prepared from phenyl isothiocyanate and used as educts for syntheses of lavandulal and ar-curcumene. Also ethyl furane 3-carbodithioate (68), as prepared from the nitrile, has found application in syntheses of the natural products egona ketone and ar-turmerone. ...
