We have developed an efficient synthesis of both enantiomers of a key azadiene for the preparation of 5-aza analogues of angucyclinones through a hetero Diels–Alder reaction. These dienes were efficiently prepared via a 4-step procedure from known and readily available chiral diketoesters.
我们已经开发了一种关键氮杂二烯的对映异构体的有效合成方法,用于通过杂Diels-Alder反应制备蒽环酮的5-氮杂类似物。这些二烯是通过四步法从已知的和容易获得的手性二酮酸酯中有效制备的。
