Pinto, Angelo C.,Pereira, Anibal L.,Kelecom, Alphonse,Porreca, Lucia M.,Ribeiro, Nubia M.,Barnes, Roderick A.
, p. 4689 - 4692 (2007/10/02)
Oxidation with tert-butyl chromate of a methylene group adjacent to a double bond or aromatic ring has been effected in excellent yield with the majority of a selected group of diterpenes and triterpenes.Some of the factors influencing the course of the reaction are discussed.Keywords - oxidation; tert-butyl chromate; diterpene; triterpene; ketone
Phase-transfer Catalysed Allylic Oxidation of Hindered Double Bonds in a Rigid Framework by Sodium Periodate
Singh, Chandan
, p. 859 (2007/10/02)
The reaction of sodium periodate under phase-transfer catalysis with abietenol acetate-diethyl fumarate Diels-Alder adduct (1), β-amyrin acetate (3) and α-amyrin acetate (4) furnishes allylic oxygenated products 2, 5 and 6 respectively.This appears to be the first report of allylic oxidation by sodium periodate.
