Abstract A convenient and facile chemo-and regioselective oxidation of the allylic methylene group in a 2-phospholene ring system afforded the novel carbonyl derivatives of 2- phospholenes (2a–i). The method gives high conversion and selectivity in the formation of allylic ketones. The advantages of this oxidation method in such a five-membered pseudo sugar 2-phospholene ring are mentioned, and the oxidation is examined on several ...
