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.

The synthesis of alkylated pyrimidines was achieved via benzophenone-mediated photoinduced coupling between saturated heterocycles and sulfonylpyrimidines. The pyrimidine ring was selectively introduced at the nonacidic C(sp3)–H bond proximal to heteroatoms including oxygen, nitrogen, and sulfur. This is a coupling reaction mediated solely by photoexcited benzophenone, an organic molecule, without
The present invention provides compounds that modulate the activity of Janus kinases and are useful in the treatment of diseases related to activity of Janus kinases including, for example, immune-related diseases and cancer.
