Abstract
Stepwise dealkylation of meso-octaethylporphyrinogen 1 yields porphomethene 2 and porphodimethene 3, providing access to large quantities of these valuable intermediates. The synthetic sequence relies on SnCl⋅2 THF, Li, and HO; the extent of dealkylation depends on the amount of SnCl⋅2 THF employed.
摘要
中-八乙基卟吩原1的逐步脱烷基化反应生成卟吩2和二氢卟吩3，从而能够大量获得这些有价值的中间体。合成序列依赖于二氯化锡·2四氢呋喃、锂和氢氧根；脱烷基化的程度取决于所使用的二氯化锡·2四氢呋喃的量。
