Asymmetric synthesis of vicinal amino alcohols: xestoaminol C, sphinganine and sphingosine
摘要:
The highly diastereoselectiveanti-aminohydroxylation of α,β-unsaturated esters,viaconjugate addition of lithium (S)-N-benzyl-N-(α-methylbenzyl)amide and subsequentin situenolate oxidation with (+)-(camphorsulfonyl)oxaziridine, has been used as the key step in the asymmetric synthesis ofN,O-diacetyl xestoaminol C (41% yield over 8 steps),N,O,O-triacetyl sphinganine (30% yield over 8 steps) andN,O,O-triacetyl sphingosine (30% yield over 7 steps).
