摘要: This micro-review attempts to comprehensively cover reported reactions employing thio- and aminophosphate precursors for forming sulfur nitrogen heterocycles. All such are triggered by initial formation of an alkoxide, most commonly attack a carbon or heteroatom nucleophile onto carbonyl group. The alkoxide intermediate facilitates intramolecular transfer the phosphate group form thiolate atom anion, which then terminate anionic cascade via O-phosphate displacement reaction heterocyclic products.
