Catalytic Asymmetric Formal [4 + 1] Annulation Leading to Optically Active cis-Isoxazoline N-Oxides
Zugui Shi, Bin Tan, Wendy Wen Yi Leong, Xiaofei Zeng, Min Lu, and Guofu ZhongOrganic Letters2010 12 (23), 5402-5405Catalytic Asymmetric Formal [4 + 1] Annulation Leading to Optically Active cis-Isoxazoline N-Oxides
Zugui Shi, Bin Tan, Wendy Wen Yi Leong, Xiaofei Zeng, Min Lu, and Guofu ZhongOrganic Letters2010 12 (23), 5402-5405The catalytic asymmetric synthesis of densely functionalized cis-isoxazoline N-oxides was realized with novel use of an organocatalyst, (S)-2-(azidodiphenylmethyl)pyrrolidine (4e) (Tan, B.; Zhu, D.; Zhang, L.; Chua, P. J.; Zeng, X.; Zhong, G. Chem.−Eur. ...
Development of a Formal [4 + 1] Cycloaddition: Pd(OAc)2-Catalyzed Intramolecular Cyclopropanation of 1,3-Dienyl β-Keto Esters and MgI2-Promoted Vinylcyclopropane−Cyclopentene Rearrangement
Rockford W. Coscia and Tristan H. LambertJournal of the American Chemical Society2009 131 (7), 2496-2498Development of a Formal [4 + 1] Cycloaddition: Pd(OAc)2-Catalyzed Intramolecular Cyclopropanation of 1,3-Dienyl β-Keto Esters and MgI2-Promoted Vinylcyclopropane−Cyclopentene Rearrangement
Rockford W. Coscia and Tristan H. LambertJournal of the American Chemical Society2009 131 (7), 2496-2498A formal [4 + 1] cycloaddition of 1,3-dienyl β-keto esters has been developed. This two step process involves Pd(II)-catalyzed intramolecular cyclopropanation to produce vinylcyclopropanes and a subsequent mild vinylcyclopropane−cyclopentene rearrangement ...
A Catalytic Method for the Preparation of Polysubstituted Cyclopentanes: [3+2] Cycloaddition of Vinylidenecyclopropanes with Activated Olefins Catalyzed by Triflic Imide
Wei Li and Min ShiThe Journal of Organic Chemistry2009 74 (2), 856-860A Catalytic Method for the Preparation of Polysubstituted Cyclopentanes: [3+2] Cycloaddition of Vinylidenecyclopropanes with Activated Olefins Catalyzed by Triflic Imide
Wei Li and Min ShiThe Journal of Organic Chemistry2009 74 (2), 856-860[3+2] Cycloadditions of vinylidenecyclopropanes (VDCPs) with electron-deficient olefins, such as methyl vinyl ketone (MVK) and acrylaldehyde, proceed smoothly in the presence of a catalytic amount of triflic imide (Tf2NH) to give the corresponding ...
Diene−Titanium Complexes as Synthetic Intermediates for the Construction of Three- or Five-Membered Carbocycles
Philippe Bertus, Christine Menant, Chloé Tanguy, and Jan SzymoniakOrganic Letters2008 10 (5), 777-780Diene−Titanium Complexes as Synthetic Intermediates for the Construction of Three- or Five-Membered Carbocycles
Philippe Bertus, Christine Menant, Chloé Tanguy, and Jan SzymoniakOrganic Letters2008 10 (5), 777-780It has been shown that dienetitanium complexes exhibit substrate-dependent 1,2- or 1,4-dicarbanion reactivity. On this basis, 3-cyclopentenylamines and spiro-vinylcyclopropane lactams were easily prepared by using homoallylic Grignard reagents, Ti(O-i-Pr)...
