The (+)-sparteine-mediated lithiation-substitution of o-benzyl-N- pivaloylaniline with various ketones was investigated. The obtained highly enantioenriched tertiary alcohols were used for the synthesis of alkenyl-substituted products 12 and 13 as well as 3,3,4-trisubstituted tetrahydroquinoline derivatives 22-24. The reaction with alpha,beta- unsaturated ketones afforded highly enantioenriched 1,4-addition products 28-33 and provided a protocol for the asymmetric synthesis of highly substituted tetralin derivative 34.

Masked silylene complexes Cp?(IXy-H)(H)RuSiH2R (R = Mes (3) and Trip (4); IXy = 1,3-bis(2,6-dimethylphenyl)imidazol-2-ylidene; “IXy-H” is the deprotonated form of IXy) exhibit metallosilylene-like (LnM-Si-R) reactivity, as observed in reactions of nonenolizable ketones, enones, and tosyl azides, to give unprecedented silaoxiranyl, oxasilacyclopentenyl, and silaiminyl complexes, respectively. Notably, these silicon-containing complexes are derived from the primary silanes MesSiH3 and TripSiH3 via activation of all three Si-H bonds. DFT calculations suggest that the mechanism of formation for the silaoxiranyl complex Cp?(IXy)(H)2Ru-Si(OCPh2)Trip (6) involves coordination of benzophenone to a silylene silicon atom, followed by a single-electron transfer in which Si-bonded, non-innocent benzophenone accepts an electron from the reactive, electron-rich ruthenium center. Importantly, this electron transfer promotes an unusual 1,2-hydrogen migration to the resulting, more electron-deficient ruthenium center via a diradicaloid transition state.

A new protocol for 1,4-conjugate addition of indoles to vinyl ketones has been developed, employing Lewis acidic ionic liquid immobilized on silica, ILIS-SO2Cl, as a catalyst, which exhibited an efficient, mild and recyclable nature. The reaction condition is applicable to various vinyl ketones and indoles. The mild nature of the reaction condition showed that the acetoxy or TBDMS group in indoles was maintained intact. The catalyst was used six times resulting in 86% average yield. Georg Thieme Verlag Stuttgart.

A palladium-catalyzed intermolecular vicinal diarylation of terminal 1,3-dienes using aryldiazonium tetrafluoroborates and arylboronic acids is reported. Using this technology, two different arenes are regioselectively introduced in a vicinal fashion across the terminal alkene of a variety of terminal 1,3-dienes at ambient temperature. Through the action of a chiral bicyclo[2.2.2]octadienyl ligand at -20 C, good enantioselectivity has also been achieved.

A Pd(0)-catalyzed Hiyama coupling reaction of tetrafluoroethylene (TFE) proceeded without the use of a base to give alpha,beta,beta- trifluorostyrene derivatives. A Ni(0)-catalyzed Hiyama coupling reaction of perfluoroarenes also occurred without a base. The key intermediate in these reactions would be a transition-metal fluoride complex that is generated in situ by the oxidative addition of a C-F bond.

A novel and efficient stereo-controlled synthesis of hexahydroquinolinones via the diene-transmissive hetero-Diels-Alder reaction of cross-conjugated azatrienes with ketenes and electrophilic dienophiles

The diene-transmissive hetero-Diels-Alder (DTHDA) reactions of cross-conjugated azatrienes (divinylimines or penta-1,4-dien-3-imines) having an N-aryl, N-alkyl, or N-dimethylamino substituent have been examined. The initial reaction of the azatrienes with diphenylketene at room temperature yielded beta-lactams of [2+2] cycloadducts, which upon heating underwent [1,3]-sigmatropic rearrangement to produce the formal [4+2] cycloadducts. The reaction of N-phenylazatriene with dimethylketene or dichloroketene produced the [2+2] cycloadducts only, while the reaction of N-(dimethylamino)azatriene with dichloroketene gave the [4+2] cycloadduct without heating. When the [2+2] cycloadduct has two different vinyl substituents at C-4 of the beta-lactam ring, the regioselectivity of the rearrangement depends on steric factors and the electronic demand of the substituents. The second Diels-Alder reaction of the initial [4+2] cycloadducts with electron-deficient dienophiles (TCNE, N-phenylmaleimide) stereoselectively yielded hexahydroquinolinone derivatives. Similarly, a tandem intermolecular-intramolecular mode of the aza-DTHDA reactions produced tetracyclic nitrogen-containing heterocycles in a regio- and stereoselective manner.
