  3-(2-Alken-1-one-2-yl)indoles through the palladium-catalyzed reaction of 2-alkynyltrifluoroacetanilides with cyclic α-iodoenones

  摘要：

  alpha-Iodoenones can be efficiently employed as organic electrophiles in the Pd-catalyzed synthesis of 2, 3-disubstituted indoles from 2-alkynyltrifluoroacetanilides. Best results were obtained using the weak ligand As(Ph)(3). The methodology reported provides an efficient entry to indoles bearing a 2-alkenon-2-yl moiety linked in the 3-position, that possesses a scarcely reported substitution pattern.

  A novel palladium-catalyzed synthesis of free N−H 2,3-disubstituted indoles from arenediazonium tetrafluoroborates and 2-alkynyltrifluoroacetanilides is presented. The reaction tolerates a variety of useful substituents both in the starting alkyne and the arenediazonium salt, including bromo and chloro substituents, nitro, cyano, keto, ester, and ether groups, as well as ortho substituents such as

• Palladium-Catalyzed Cyclization of <i>o</i>-Alkynyltrifluoroacetanilides with Allyl Esters. A Regioselective Synthesis of 3-Allylindoles

  日期：1998.2.1

  The reaction of readily available o-alkynyltrifluoroacetanilides 1 with allyl esters provides a valuable new route to 3-allylindoles 3. Three basic procedures have been developed: a stepwise method based on the isolation of the N-allyl derivative 4 and its subsequent cyclization to 3 (procedure a), a one-pot reaction omitting the isolation of 4 (procedure b), and a procedure which most probably leads to the formation of 3 through a mechanism not involving the intermediacy of 4 (procedure c). In the presence of the electron-rich sterically encumbered ligand tris(2,4,6-trimethoxyphenyl)phosphine (ttmpp) the reaction exhibits remarkable regioselectivity and almost exclusive formation of 3-allylindoles with the indolyl moiety bound to the less substituted allyl terminus is usually observed. However, some loss of olefin geometry is observed.

  [GRAPHICS]A general method for the synthesis of 2-aryl and 2-heteroaryl indoles from aryl iodides and 1-alkynes through a domino copper-catalyzed process is reported. The best results have been obtained with [Cu(phen)(PPh3)(2)]NO3 in the presence of K3PO4 in toluene or dioxane at 110 degreesC. 2-Aryl and 2-heteroaryl indoles can also be isolated in good yields by using catalysts derived from CuI and PPh3 in dioxane at 110 degreesC.
