Dolewski, Ryan D.; Fricke, Patrick J.; McNally, Andrew published the article 《Site-Selective Switching Strategies to Functionalize Polyazines》. Keywords: functionalize polyazine preparation; switchable control carbon phosphorus bond formation.They researched the compound: Boc-D-Prolinol( cas:83435-58-9 ).Reference of Boc-D-Prolinol. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:83435-58-9) here.
Many drug fragments and therapeutic compounds contain multiple pyridines and diazines. Developing site-selective reactions where specific C-H bonds can be transformed in polyazine structures would enable rapid access to valuable derivatives Authors present a study that addresses this challenge by selectively installing a phosphonium ion as a versatile functional handle. Inherent factors that control site-selectivity are described along with mechanistically driven approaches for site-selective switching, where the C-+PPh3 group can be predictably installed at other positions in the polyazine system. Simple protocols, readily available reagents, and application to complex drug-like mols. make this approach appealing to medicinal chemists.
