N-1 Oxidation of Adenine Substituted at N-9 by an Olefinic Chain
摘要:
The oxidation of 9-vinyladenine derivatives (1a-c) with m-chloroperoxybenzoic acid (MCPBA) leads selectively to the corresponding N-1 oxides (2a-c) and when the 6-amino group is protected, the oxidation occurs on the double bond of the olefinic chain to give the epoxides (6a, b) selectively.
