Regioselective Synthesis of New 1-Aminopyrroles and 1-Amino-4,5,6,7-tetrahydroindoles by One-Pot ‘Conjugate Addition/Cyclization’ Reactions of 1,3-Bis(silyl enol ethers) with 1,2-Diaza-1,3-butadienes.

Unknown functionalized 1-aminopyrroles and 1-amino-4,5,6,7-tetrahydroindoles were prepared under mild conditions and with excellent yields by one-pot ‘conjugate addition/cyclization’ reactions of 1,3-bis(silyl enol ethers) with 1,2-diaza-1,3-butadienes. [ABSTRACT FROM AUTHOR]
