A Facile Synthesis of 3-Substituted-2-aminothiophenes and 1,3-Disubstituted-2-methylthiopyrroles
摘要:
Electron-rich 3-functionalized-2-aminothiophenes 6 and 1,3-disubstituted-2-methylthiopyrroles 10 were synthesized from substituted allyl benzotriazoles 2 and isothiocyanates 3 via condensation and subsequent heterocyclization.
A highly enantioselective allylic substitution of sodium benzotriazolide has been attained in the presence of [Ir(COD)Cl](2)/phosphoramidite ligand L1 together with K3PO4 as an additive, producing enantioen-riched allylbenzotriazole compounds with up to 98% ee.
