A wagner–meerwein rearrangement of the cholestane skeleton induced by a long-range intramolecular hydrogen abstraction by alkoxyl radicals; the first example of long-range intramolecular addition of an alkoxyl radical to a carbon–carbon double bond

Abstract

The formation of a novel macrocyclic ether lactone, induced by a series of long-range Intramolecular reactions involving the first example of a long-range Intramolecular addition of an alkoxyl radical to a remote carbon–carbon double bond, accompanies the long-range Intramolecular oxygenation of C(15) of the cholestane skeleton.
