One catalyst for two distinct reactions: Sequential asymmetric hetero Diels-Alder reaction and diethylzinc addition
Du, Haifeng,Zhang, Xue,Wang, Zheng,Ding, Kuiling
, p. 9465 - 9477 (2005)
This paper describes the successful development of a series of chiral zinc catalysts containing (R)-3,3′-Br2-BINOL ligand and various diimine activators for enantioselective HDA reaction of Danishefsky's diene with aldehydes through a combinato
Electronic effects on the acidity of phosphorus(III) triflates
Renard, Sylvie L.,Kee, Terence P.
, p. 516 - 521 (2007/10/03)
A range of chiral phosphorus(III) triflates has been prepared and their donor-acceptor behaviour towards the representative donor 4-phenylpyridine investigated. Correlations between 31P-NMR shifts, relative binding strengths (Kr) and
Bis(imine)-copper(II) complexes as chiral lewis acid catalysts for the Diels-Alder reaction
Evans, David A.,Lectka, Thomas,Miller, Scott J.
, p. 7027 - 7030 (2007/10/02)
We report the Diels-Alder reactions of imide-derived dienophiles 2a-2d and 4b-4d with cyclopentadiene catalysed by square-planar Cu(OTf)2-bis(imine) complexes. The 2,6-dichlorophenyl-substituted ligand 1a was found to be generally the most effe
