(R)-4-Phenyl-5,5-dimethyl-oxazolidin-2-one, readily available from d-phenylglycine, is shown to be an effective chiral auxiliary for stereoselective conjugate additions to attached α,β-unsaturated N-acyl moieties. Its utility is demonstrated by the asymmetric synthesis of the antifungal, antibacterial (−)-Aplysillamide B.
可以容易地从d-苯基甘氨酸获得的(R)-4-苯基-5,5-二甲基-恶唑烷-2--2-酮是对立体选择性共轭加成到连接的α,β-不饱和N-酰基部分的有效手性助剂。抗真菌,抗菌(-)-Aplysillamide B的不对称合成证明了其实用性。
