Zirconium-mediated diastereoselective coupling reactions of chiral aldimine: Remarkable temperature-dependence of chiral induction
摘要:
Zr-Mediated coupling reactions of aldehyde with chiral aldimine which is derived from benzaldehyde and (R)-phenylglycinol methyl ether showed a remarkable temperature effect on the sense of chiral induction to yield amino alcohol derivatives with high diastereoselectivities.

Sigmatropic rearrangement of trichloracetimidates derived from syn monoprotected allylic diols 3 resulting from the condensation of vinylalanes or cuprates with α-alkoxyaldehydes afforded diastereomerically pure allylic amines 6. The oxidative cleavage of these amines allowed the access to α,α-disubstituted α-aminoacids in high enantiomeric purity.
