  Metal-Free Synthesis of 2-Oxindoles via PhI(OAc)₂-Mediated Oxidative C–C Bond Formation

  摘要：

  The series of 3-monofunctionalized 2-oxindoles 2 were conveniently synthesized from reactions between anilide 1 and phenyliodine(III) diacetate (PIDA) through hypervalent iodine mediated C(sp(2))-C(sp(2)) bond formation followed by a subsequent deacylation reaction. This metal-free method, shown to provide direct access to an important oxindole intermediate, could be applied to the total synthesis of naturally occurring horsfiline.

  Dirhodium tetraacetate catalyzed carbon-hydrogen insertion reaction in N-substituted .alpha.-carbomethoxy-.alpha.-diazoacetanilides and structural analogs. Substituent and conformational effects

  摘要：

  A series of acyclic alpha-carbomethoxy-alpha-diazoacetanilides with different N-substituents, 5a-k, was prepared and the rhodium(II) acetate catalyzed reactions studied. It was found that the rhodium carbenoid reaction with these compounds occurred only at the N-substituent; when the N-substituent is a propargyl group, rhodium carbenoid addition to the triple bond is favored, resulting, ultimately, in the formation of a bicyclic furan derivative 8. With an N-(tert-butyloxycarbonyl)methyl substituent, interception of the rhodium carbenoid by the ester carbonyl oxygen occurred preferentially to give, eventually, 1,4-oxazine derivatives 9 and 9'. For N-alkyl substituents, rhodium carbenoid carbon-hydrogen (C-H) insertion into the alkyl group to give 2-azetidinone and/or 2-pyrrolidinone derivatives was observed. The chemoselectivity of the rhodium carbenoid C-H insertion can be altered by the use of the alpha-acetyl and alpha-phenylsulfonyl substituents. In these cases, exclusive C-H insertion at the N-aryl moiety resulted to give 2(3H)-indolinone products. However, the alpha-substituent effect on the chemoselectivity of the insertion reaction is easily overridden by conformational effects about the amide N-C(O) bond as revealed by the insertion reactions of the conformationally rigid compounds 20a-c. The alpha-substituent effects are reestablished when conformational rigidity is removed, as exemplified by the rhodium carbenoid insertion reactions of compounds 29a,b.

  The intramolecular C(sp3)–H/C(sp2)–H cross-coupling of 1,3-dicarbonyl compounds has been achieved through Cp2Fe-catalyzed electrochemical oxidation. The key to the success of these dehydrogenative cyclization reactions is the selective activation of the acidic α-C–H bond of the 1,3-dicarbonyl moiety to generate a carbon-centered radical.
