Ring Opening of Cyclic Sulfamidates with Magnesiated Heterocycles: Expedient Synthesis of Highly Functionalised Azaindolines and Azatetrahydroquinolines
摘要:
Magnesiated chloropyrimidine and chloropyridine derivatives, obtained by deprotonation with TMPMgCl center dot LiCl at room temperature, undergo facile ring-opening reactions with five-and six-membered N-Boc and N-Bn cyclic sulfamidates. After an acidic workup, the adducts undergo rapid intramolecular cyclisation on basification to give highly functionalised stereodefined azaindolines and azatetrahydroquinolines in good yields.
