Cinchoninone, CigHaaONj, produced by the oxidation of either cinchonine or cinchonidine by chromic acid in presence of sulphuric acid forms pale yellow prisms, m.p. 126-7°, [a]j) -(-71° to -(-76°, is sparingly soluble in light petroleum, easily in ether or chloroform and insoluble in water. The hydrochloride forms minute colourless needles, m.p. 245-7°, [a]r) -(-175-9°. By further oxidation with chromic acid, cinchoninone yields cinchoninic acid and meroquinenine (meroquinene).

Finally, proof was obtained that the aliphatic portion of the aspidocarpine molecule was identical with the corresponding portion of aspido-spermine by oxidation of the two compounds with chromic acid in dilute sulfuric acid. In both cases, the aromatic ring was destroyed and there was isolated the a-keto amide (LI), mp 224°-225°, [a]D —132° (chloroform). The identity of this oxidation product shows not only that aspidocarpine (XLIV) and aspidospermine (II) have an identical skeleton but also that they have the same absolute configuration at all four centers.

Dichloroethyl sulphone may be obtained by the oxidation of dichloroethyl sulphoxide or sulphide. Thus by the action of potassium permanganate on dichloroethyl sulphide, Steinkopf obtained the sulphone as colourless crystals melting at 52° C. and boiling at 179° to 181° C. at 14-15 mm. of mercury pressure. This compound is sparingly soluble in water (o-6 gm. in 100 ml. at 20° C., and 2-4 gm. in 100 ml. at 100° C.) and is only slightly hydrolysed. It is soluble in alcohol (7-1 gm. in 100 ml. at 20° C.), ether, chloroform, etc. Helfrich and Reid obtained the sulphone by treating the sulphoxide in the cold with a solution of chromic acid in sulphuric acid.

Glycosmicine was obtained by potassium permanganate, periodic acid (72), or chromic acid (75) oxidation of arborine (1). This fact and the spectral data indicate structure 4 for this alkaloid, which was confirmed by comparison with synthetic material prepared from 7V-methylanthranilamide and ethyl chloroformate.

Oxidations-The use of a two phase ether-aqueous chromic acid system for oxidation of secondary alcohols to ketones has been reported to afford, in a rapid fashion, ketones which are remarkably free of isomerized and side products. Amine oxides can be prepared in 90% yield from the corresponding amines, using m-chloroperbenzoic acid in chloroform, followed by purification of the reaction mixture on an alumina column. ...
