As a part of our ongoing research on the synthesis of bioactive constituents or molecules by using an organocatalytic approach, enantioselective total syntheses of ligraminol D and ligraminol E were achieved starting from a commercially available nonchiral aldehyde. Key steps in this synthesis were an asymmetric α-aminoxylation of an aldehyde and a Mitsunobu reaction.
作为我们正在进行的使用有机催化方法合成生物活性成分或分子的研究的一部分,从市售的非手性醛开始实现了 ligraminol D 和 ligraminol E 的对映选择性全合成。该合成的关键步骤是醛的不对称 α-氨氧基化和光信反应。

Abstract Efficient syntheses of optically active neolignans ligraminol D and E were achieved in four simple steps starting from easily available chiral benzyl glycidyl ethers. The products were obtained in good overall yields and high enantioselectivities. The protocol might also be useful in the synthesis of other ligraminols or related neolignans.
