Liu, Dong-Dong,Sun, Tian-Wen,Wang, Kuang-Yu,Lu, Yong,Zhang, Su-Lei,Li, Yuan-He,Jiang, Yan-Long,Chen, Jia-Hua,Yang, Zhen
, p. 5732 - 5735 (2017)
Asymmetric total synthesis of structurally intriguing and highly oxygenated lancifodilactone G acetate (7) has been achieved for the first time in 28 steps from a cheap commodity chemical, 2-(triisopropylsiloxy)-1,3-butadiene.
Catalytic and Enantioselective Diels-Alder Reactions of (E)-4-Oxopent-2-enoates
Zhang, Su-Lei,Lu, Yong,Li, Yuan-He,Wang, Kuang-Yu,Chen, Jia-Hua,Yang, Zhen
, p. 3986 - 3989 (2017)
Novel oxazaborolidines activated by the strong acid triflimide or AlBr3 form cationic chiral catalysts. These are effective catalysts for highly regio- and enantioselective Diels-Alder reactions using substituted (E)-4-oxopent-2-enoates as dienophiles.
Cationic Chiral Fluorinated Oxazaborolidines. More Potent, Second-Generation Catalysts for Highly Enantioselective Cycloaddition Reactions
Mahender Reddy, Karla,Bhimireddy, Eswar,Thirupathi, Barla,Breitler, Simon,Yu, Shunming,Corey
supporting information, p. 2443 - 2453 (2016/03/08)
The coordination of chiral ligands to Lewis acid metal derivatives, a useful strategy for enantioselective, electrophilic catalysis, generally leads to a lower level of catalytic activity than that of the original uncomplexed compound. Activation by furth
Highly Enantioselective diels-alder reactions of maleimides catalyzed by activated chiral oxazaborolidines
Mukherjee, Santanu,Corey
experimental part, p. 632 - 635 (2010/06/17)
[Chemical equation presented] Diels-Alder reactions of various combinations of maleimides and 1,3-dienes with cationic oxazaborolidines as catalysts have been shown to be highly efficient and enantioselective.
Synthesis and characterization of triarylborthiins, Ar3B3S3 (Ar=4-MeC6H4, 3-MeC6H4, 2-MeC6H4, 4-EtC6H4, and 3,5-Me2C6H3)
Beckett, Michael A.,Minton, Paul R.,Werschkun, Barbara
, p. 37 - 42 (2007/10/02)
The air/moisture-sensitive triarylborthiins, Ar3B3S3 (Ar=4-MeC6H4, 3-MeC6H4, 2-MeC6H4, 4-EtC6H4, and 3,5-Me2C6H3), have been prepared by the reaction of ArBBr2 with HgS in benzene at reflux and have been characterized by 11B NMR and IR spectroscopy and ma
A New Borylation Method for Alkylbenzene and Polystyrene
Paetzold, Peter,Hoffmann, Juergen
, p. 3724 - 3733 (2007/10/02)
The borylation of alkylbenzenes by Hal2BH (Hal = F, Cl, Br) gives H2 and a mixture of m- and p-alkyl(dihaloboryl)benzenes.In the case of bulky alkyl groups, such as isopropyl, tert-butyl, these are partially split off as R - H and RBHal2.The phenyl groups in polystyrene-divinylbenzene copolymers undergo borylation with Br2BH in a 55percent yield.
