and formylation. Condensation of these aldehydes with activated pyrroles in the presence of phosphoryl chloride provides analogues of prodigiosin, which differ from the natural products in the nature of the heteroatoms. gas-phase reactions - heterocycles - pyrroles - prodigiosins
由合适的3-羟基吡咯或3-羟基噻吩通过以下方法制备3-甲氧基-5-(2-噻吩基)噻吩-2-甲醛和3-甲氧基-1-甲基-5-(2-噻吩基)吡咯-2-甲醛区域选择性的O-烷基化和甲酰化。这些醛与活化的吡咯在磷酰氯存在下的缩合提供了prodigiosin的类似物,其与天然产物的杂原子性质不同。 气相反应-杂环-吡咯-prodigiosins
