  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).

• Cross-Coupling of Nonactivated Primary and Secondary Alkyl Halides with Aryl Grignard Reagents Catalyzed by Chiral Iron Pincer Complexes

  Abstract Iron(III) bisoxazolinylphenylamido (bopa) pincer complexes are efficient precatalysts for the cross-coupling of nonactivated primary and secondary alkyl halides with phenyl Grignard reagents. The reactions proceed at room temperature in moderate to excellent yields. A variety of functional groups can be tolerated. The enantioselectivity of the coupling of secondary alkyl halides is low.

  The first Ni-catalyzed Suzuki–Miyaura coupling of alkyl halides with alkenyl-(9-BBN) reagents is reported. Both primary and secondary alkyl halides including alkyl chlorides can be coupled. The coupling method can be combined with hydroboration of terminal alkynes, allowing the expedited synthesis of functionalized alkyl alkenes from readily available alkynes with complete (E)-selectivity in one pot

• NiH-Catalyzed Reductive Relay Hydroalkylation: A Strategy for the Remote C(sp³ )−H Alkylation of Alkenes

  The terminal‐selective, remote C(sp3)−H alkylation of alkenes was achieved by a relay process combining NiH‐catalyzed hydrometalation, chain walking, and alkylation. This method enables the construction of unfunctionalized C(sp3)−C(sp3) bonds under mild conditions from two simple feedstock chemicals, namely olefins and alkyl halides. The practical value of this transformation is further demonstrated

  烯烃的末端选择性远程C（sp 3）-H烷基化是通过结合NiH催化的加氢金属化，链行走和烷基化的中继过程实现的。该方法能够在温和条件下由两种简单的原料化学品即烯烃和烷基卤化物构造未官能化的C（sp 3）-C（sp 3）键。在低催化剂负载下，烯烃异构混合物的大规模和区域会聚烷基化进一步证明了这种转化的实用价值。
