  Highly regioselective synthesis of substituted tetrahydroquinolines by palladium-catalyzed cyclization of substituted 2-amidophenylmalonates with 1,4-diacetoxybut-2-ene

  摘要：

  The reaction of 2-amidophenylmalonates with 1,4-diacetoxybut-2-ene in the presence of a palladium catalyst is described. Substituted tetrahydroquinolines having a vinyl group at the 3- or 2-position were synthesized, in which the regioselectivities of the double allylic substitution reactions have been altered depending on the substituent on the amino group.

  Regio- and enantioselective synthesis of functionalized tetrahydroquinolines by palladium-catalyzed cyclization of 2-amidophenylmalonates with allylic bisacetates

  摘要：

  A palladium-catalyzed cyclization of 2-amidophenylmalonates with allylic bisacetates is described. Tetrahydroquinolines having a vinyl group at the 3- or 2-position were produced, in which the regioselectivity of the resulting products was altered depending on the substituent on the amino group. The product was transformed to the azabicyclo[3.3.1]nonene via the ring-closing metathesis. Enantioselective reactions also successfully proceeded in the presence of (S)-BINAP to give the optically active tetrahydroquinoline with high enantioselectivity. (C) 2012 Elsevier Ltd.

  Cu(II)/Mn(III)-mediated synergistic radical N-heteroannulation reaction of [60]fullerene with N-sulfonylated o-amino-arylmalonates has been developed for the direct and efficient construction of [60]fullerene-fused tetrahydroquinoline derivatives. A plausible mechanism for the formation of fullerotetrahydroquinolines is proposed, and the electrochemical properties of the obtained fullerene adducts
