Diversity-oriented synthesis (DOS) of a collection of novel, highly functionalized Δ 3 -pyrrolines has been accomplished by a AgNO 3 -catalyzed cyclization reaction of allenic amino acids that proceeds with transfer ofchiral information. A new mode of cyclization of allenic benzoyl-protected amines in the Ag(I)-catalyzed reaction leading to oxazines was observed.
一系列新的、高度官能化的 Δ 3 -吡咯啉的多样性导向合成 (DOS) 已通过 AgNO 3 催化的丙二酸氨基酸环化反应完成,该反应进行手性信息的转移。观察到在 Ag(I) 催化的反应中丙二烯苯甲酰基保护的胺环化的新模式,导致恶嗪。
