2-Hydroxymethyl-1-methylsulfonyl-3,4-disubstituted pyrroles and 2-hydroxymethyl-3,4-disubstituted pyrroles were effectively converted into the corresponding 2-(substituted methyl)pyrrole derivatives by the reaction with various nucleophiles in the presence of base. These products were further transformed to the corresponding porphyrins regioselectively under almost neutral or basic conditions.
2-羟甲基-1-甲基磺酰基-3,4-二取代吡咯和2-羟甲基-3,4-二取代吡咯在碱存在下与各种亲核试剂反应有效地转化为相应的2-(取代甲基)吡咯衍生物. 这些产物在几乎中性或碱性条件下进一步区域选择性地转化为相应的卟啉。
