12 of a type useful in the synthesis of naturally occurring chlorins, isobacteriochlorins, and corrins have been prepared by a process involving Nicholas-Schreiber condensation to afford acetylenic amides 13, followed by either n-Bu4NF or LiA1(NHBn)4-catalyzed ring closure.
环状烯酰胺12在天然存在的二氢卟酚,isobacteriochlorins,和咕啉的合成有用的类型的已经制备通过涉及尼古拉斯-施雷伯缩合,得到炔属酰胺的方法13,随后要么Ñ -Bu 4 NF或LiA1(NHBn)4-催化的闭环。
