(S)-2-Aryl-4,4-diphenyl-3,1,2-oxazaboro[3.3.0]octanes: Efficient catalysts for the asymmetric borane reduction of electron-deficient ketones
Liu, Han,Xu
, p. 68 - 72 (2006)
The obvious influence of electronic effects of ketones on the enantioselectivities was observed previously in the oxazaborolidine-catalyzed asymmetric borane reduction of ketones. On the basis of the catalytic reduction mechanism, the electronic effect of
Enantioselective synthesis of polyketide segments through vinylogous Mukaiyama aldol reactions
Simsek, Serkan,Kalesse, Markus
, p. 3485 - 3488 (2009)
The synthesis of polyketide segments through the vinylogous Mukaiyama aldol reaction is reported. The use of chiral oxazaborolidines allows using terminal substituted ketene acetals and provides access to extended segments and two new chiral centers.
Enantioselective Cyclopropanation/[1,5]-Hydrogen Shift to Access Rauhut-Currier Product
Kim, Seung Tae,Pandit, Rameshwar Prasad,Yun, Jaesook,Ryu, Do Hyun
supporting information, p. 213 - 217 (2021/01/09)
A Michael addition initiated cyclopropanation/[1,5]-hydrogen shift has been developed for the enantioselective synthesis of Rauhut-Currier products. The reaction of α-alkyl diazoesters and in situ generated o-quinone methides proceeds in the presence of c
Enantioselective Strecker and Allylation Reactions with Aldimines Catalyzed by Chiral Oxazaborolidinium Ions
Kang, Ki-Tae,Park, Sang Hyun,Ryu, Do Hyun
supporting information, p. 6679 - 6683 (2019/09/12)
Chiral oxazaborolidinium ion (COBI)-catalyzed enantioselective nucleophilic addition reactions of aldimines using tributyltin cyanide and allyltributylstannane have been developed. Various α-aminonitriles and homoallylic amines were synthesized in high yi
