The general synthesis of (Z)-α,β-didehydroamino aldehydes 3 was accomplished by the reduction of (Z)-α,β-didehydroamino acid esters with lithium aluminum hydride followed by Swern oxidation. Subsequent Grignard reaction of 3 with alkylmagnesium halides was carried out to give various N-protected amino alkenols and amino alkadienols.
(Z)-δ,δ²-二脱氢
氨基醛 3 的一般合成是通过用
氢化铝锂还原 (Z)-δ,δ²-二脱氢
氨基酸酯,然后进行 Swern 氧化反应完成的。随后,3 与烷基卤化
镁进行格氏反应,得到各种 N 保护的
氨基烯醇和
氨基烷二烯醇。
