Synthesis of new chiral mixed cis-tetraheterodecalines by highly selective cyclization of N,N′-bisalkyl 2,3-diaminobutanediols

Chiral secondary vic-diamines of diaminobutanediols have been efficiently prepared from L-tartaric acid. Their selective cyclization led to cis-tetraheterodecalines having a (1S,6S)-2,7-diaza-4,9-dioxa[4.4.0]decane core system. Georg Thieme Verlag Stuttgart.

Asymmetric cyclopropanation catalyzed by C2-symmetric bi(oxazolines)

C2-symmetric bi(oxazolines) 3a-e were prepared in three steps based on a tartaric-derived vicinal diamine as common precursor. These chiral ligands were studied with respect to their directive influence on the enantioselective copper catalyzed

Synthesis of new C2-symmetric bioxazoles and application as chiral ligands in asymmetric hydrosilylation

New C2-symmetric chiral (4S,4'S)-bioxazoles 3a and 3b, possessing chirality on their backbone, were synthesized efficiently starting from L-tartaric acid. The structure of 3a was determined by X-ray crystal structure analysis. With these novel
