Palladium-catalyzed pseudo-domino cyclizations: An easy entry toward polycondensed pyrrolidone derivatives
Lemaire, Sébastien,Prestat, Guillaume,Giambastiani, Giuliano,Madec, David,Pacini, Barbara,Poli, Giovanni
, p. 291 - 300 (2003)
A new type I palladium-catalyzed pseudo-domino process is developed, in which a single Pd-based catalytic system promotes two mechanistically unrelated, sequential catalytic cycles in chronologically distinct order. Suitable precursors undergo an allylic
Synthesis of substituted γ- And δ-lactams based on titanocene(III)-catalysed radical cyclisations of trichloroacetamides
Diaba, Fa?za,Gómez-Bengoa, Enrique,Cuerva, Juan M.,Bonjoch, Josep,Justicia, José
, p. 55360 - 55365 (2016/07/06)
A new procedure for the synthesis of γ- and δ-lactams based on a Cp2TiCl-catalysed cyclisation of trichloroacetamides under mild reaction conditions is reported. Theoretical studies supported the observed regioselectivity in the cyclisations and the mechanism involved in the dehalogenation process.
Pd(0)-catalyzed allylic alkylation/Heck coupling in domino sequence
Poli, Giovanni,Giambastiani, Giuliano,Pacini, Barbara
, p. 5179 - 5182 (2007/10/03)
A new molecular queuing process has been achieved, in which a single Pd-based catalytic system promotes two unrelated, sequential catalytic cycles in chronologically distinct order. This study demonstrates also that allylic alkylations can be catalyzed by the Herrmann's phosphapalladacycle, a result that further supports the involvement of a Pd(0) species in its mechanism of action.
Synthesis of γ-Butyrolactams by the Palladium-Catalyzed Cyclization of N-Allylbromoacetamides
Yang, Shyh-Chyun,Shea, Fang-Rong
, p. 969 - 972 (2007/10/03)
N-Allylbromoacetamides undergo cyclizatlon to give γ-butyrolactams in the presence of palladium catalysts and a base. - Key words: Palladium-catalyzed cyclization; γ-Butyrolactam.
New synthesis of heterocycles by use of palladium catalyzed cycli zation of α-haloamide with internal double bond
Mori, Miwako,Kanda, Nana,Oda, Izumi,Ban, Yoshio
, p. 5465 - 5474 (2007/10/02)
α-Haloamide having internal double bond was allowed to react with a catalytic amount of Pd(PPh3)4 in the presence of base to produce a cyclized product in a fairly good yield possibly through the intermediate of -alkylmetal complex. By use of this method, five and six membered lactams, pyrrolizidine and quinolizidine derivatives were synthesized in fairly good yields.
CYCLIZATION OF α-HALOAMIDE WITH INTERNAL DOUBLE BOND BY USE OF THE LOW-VALENT METAL COMPLEX
Mori, Miwako,Oda, Izumi,Ban, Yoshio
, p. 5315 - 5318 (2007/10/02)
The α-haloamide having internal double bond was allowed to react with a catalytic amount of Pd(PPh3)4 in the presence of proton sponge to produce a cyclized product in a fairly good yield possibly through the intermediation of ?-alkylmetal complex althoug
