摘要

3e-g 8a-c chromatography. In contrast, alkylation with benzyl bromide produced mainly the 2- benzyl compound 3g which could be isolated in 75% yield. The deblocking of this compound to 2-benzylpyrrole (le) was described above, and thus it would appear that this synthetic sequence may indeed have some promise as a source of 2-alkylpyrroles. In this regard, it was recently reported'that 3a could, in fact, be metalated with n-butyllithium at 0" ...
