scheme or table, p. 7707 - 7719 (2010/10/21)
The synthesis of chiral, nonracemic butadienylcarbinols by employing intermediate (trimethylsilyl)methylallenic alcohols is described. Allenic alcohols are obtained by treatment of aldehydes with (4-bromobut-2-ynyl) trimethylsilane in the presence of a ca

A new preparation of the tridentate bis-oxazoline carbazole ligand 1 is described. This method features direct formation of the amide, which is a precursor of the ligand l, via the Pd-catalyzed amidation and following BF3 · OEt2 medi
Asymmetric catalysis of Nozaki-Hiyama allylation and methallylation with a new tridentate bis(oxazolinyl)carbazole ligand

, p. 1140 - 1141 (2007/10/03)
This work describes the development of a new tridentate ligand effective for the asymmetric catalysis of Nozaki-Hiyama allylation and methallylation. Various aldehydes were allylated or methallylated with good enantioselectivity (86-96%), and a key interm
