An efficient preparation of 1-phenylsulfonylindolyl methyl sulfoxides using KF/m-CPBA
摘要:
A variety of 1-phenylsulfonylindolylmethyl sulfides are selectively oxidized to the corresponding sulfoxides using a hitherto unexplored KF/m-CPBA system. A major advantage is the absence of over-oxidation. (c) 2005 Elsevier Ltd. All rights reserved.
