  Synthesis of 3-Iodoindoles by the Pd/Cu-Catalyzed Coupling of N,N-Dialkyl-2-iodoanilines and Terminal Acetylenes, Followed by Electrophilic Cyclization

  摘要：

  3-lodoindoles have been prepared in excellent yields by coupling terminal acetylenes with N,N-dialkyl-o-iodoanilines in the presence of a Pd/Cu catalyst, followed by an electrophilic cyclization of the resulting N,N-dialkyl-o-(1-alkynyl)anilines using I-2 in CH2Cl2. Aryl-, vinylic-, alkyl-, and silyl-substituted terminal acetylenes undergo this process to produce excellent yields of 3-iodoindoles. The reactivity of the carbon-nitrogen bond cleavage during cyclization follows the following order: Me > n-Bu, Me > Ph, and cyclohexyl > Me. Subsequent palladium-catalyzed.Sonogashira, Suzuki, and Heck reactions of the resulting 3-iodoindoles proceed smoothly in good yields.

  Cascade Electrophilic Iodocyclization: Efficient Preparation of 4-Iodomethyl Substituted Tetrahydro-β-carbolines and Formal Synthesis of Oxopropaline G

  摘要：

  4-Iodomethyl substituted tetrahydro-beta-carbolines, the core structure of numerous natural products and bioactive molecules, are readily prepared via I-2-promoted cascade electrophilic cyclization. The reactivity differences of olefins and alkynes ensure that the reaction proceeds smoothly. This methodology was successfully applied to the formal synthesis of oxopropaline G.

  Born to couple: The Pd(OAc)2‐catalyzed reaction of o‐alkynylanilines (1) with o‐alkynylbenzamides (2) affords the cyclizative cross‐coupling products 3 in good to excellent yields. Three bonds are created in the formation of two heterocycles tethered by a tetrasubstituted double bond. Mechanistic studies indicate that the reaction is initiated by aminopalladation with subsequent oxypalladation, N‐demethylation

  A palladium‐catalyzed cyclizative cross‐coupling of two o‐alkynylanilines to 2,3′‐bisindoles under aerobic oxidative conditions was developed. Mechanistic studies suggested that the two catalytic cycles, namely the formation of 3‐alkynylindoles 8 and their subsequent cyclization to bisindoles 5, are temporally separated. The aminopalladation of 3‐alkynylindoles 8 occurred only after all the N,N‐di

  A wide variety of N-alkyl-3-iodoindoles are readily prepared under very mild reaction conditions by the palladium/copper-catalyzed cross-coupling of N,N-dialkyl-o-iodoanilines and terminal alkynes, followed by electrophilic cyclization by I-2. Alkyl-, aryl-, and vinylic-substituted alkynes all undergo iodocyclization in excellent yields.
