An efficient preparation of 1-phenylsulfonylindolyl methyl sulfoxides using KF/m-CPBA
Mohanakrishnan, Arasambattu K.,Ramesh, Neelamegam
, p. 4231 - 4233 (2007/10/03)
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.
Preparation of benzindole compounds from naphthalene compounds
-
, (2008/06/13)
The invention relates to a process for preparing a substituted 2-amino-benz[cd]indole of the Formula I: STR1 The nitro group of a substituted 1-nitro-8-cyano-naphthalene compound is reduced to an amine group to form a substituted 1-amino-8-cyano-naphthalene compound, which is cyclized to form the substituted 2-amino-benz[cd]indole. The reduction and cyclization may be effected in a one-pot procedure using a reducing agent such as stannous chloride, which generates an acid that cyclizes the reduction product. The syntheses of the 1-nitro-8-cyanonaphthalene compound and its precursors are also described.
