A Novel Polonovski Rearrangement of the Uleine Skeleton
Blechert, Siegfried
, p. 2073 - 2082 (2007/10/02)
Modified Polonovski reaction of the alkaloid uleine (3) and subsequent treatment with oxygen afford dasycarpidone (8) in 65percent yield.Polonovski reaction of 1,13-dihydrouleine yields uleine.After formation of the corresponding N-oxides, 3 and 10a have been allowed to react with acyl halides giving halogenated uleine derivatives.The traditional mechanism cannot account for the formation of the reaction products.
