  Oxidative Radical Cyclization of (.omega.-Iodoalkyl)indoles and Pyrroles. Synthesis of (-)-Monomorine and Three Diastereomers

  摘要：

  Addition of excess hydrogen peroxide (10 equiv) to a sonicated solution of FeSO4:7H(2)O (1 equiv) in Dh ISO containing the N-(omega-iodoalkyl)indoles 4, 5, 11, and 13 effected oxidative radical cyclization to 6, 7, 14, and 15, respectively. The (omega-iodoalkyl)pyrroles 21, 22, 27, 38, and 49 underwent analogous cyclization reactions to 23, 24, 28, 39, and 50, respectively. The regiochemistry of these radical cyclization reactions was correctly predicted by FMO calculations in all cases but one. For compound 38, FMO calculations indicated that radical attack should take place at both C-3 and C-5. Only the product of cyclization at C-5, i.e., 39, was observed. The enantiomerically pure bicyclic ketone 42, prepared by the above technique from the iodide 53, was converted into 55 which, on catalytic reduction (H-2/Rh-A1(2)O(3)), gave a mixture of (-)-monomorine (40) and three of its diastereomers 56-58 (see, however, Note Added in Proof).

  In a pinch: The nickel pincer complex 1 catalyzes the cross‐coupling of the title compounds with remarkable substrate scope and functional group tolerance. A nickel/alkynyl species was isolated and shown to be catalytically competent. THF=tetrahydrofuran, O‐TMEDA=bis[2‐(N,N‐dimethylaminoethyl)] ether.

  A nickel(II) pincer complex [((Me)NN(2))NiCl] (1) catalyzes Kumada-Corriu-Tamao cross coupling of nonactivated alkyl halides with aryl and heteroaryl Grignard reagents. The coupling of octyl bromide with phenylmagnesium chloride was used as a test reaction. Using 3 mol % of 1 as the precatalyst and THF as the solvent, and in the presence of a catalytic amount of TMEDA, the coupling product was obtained
