The multicomponent condensation of various β-dicarbonyl compounds, acrolein and (S)-2-phenylglycinol was found to provide a one-pot access to chiral 6-carbonyl-3-phenyl-2,3,8,8a-tetrahydro-7H-[1,3]oxazolo[3,2-a]pyridines. The value of this methodology is illustrated by the short and efficient synthesis of (-)-lupinine.
发现多种β-二羰基化合物、丙烯醛和(S)-2-苯基甘氨酸醇的多组分缩合反应,可以一锅法合成手性6-羰基-3-苯基-2,3,8,8a-四氢-7H-[1,3]恶唑并[3,2-a]吡啶。通过(-)-羽扇豆碱的简短高效合成,展示了这种方法的价值。
