Abstract: Two complementary cascade cyclization reactions were described, namely KHSO4-promoted [1+2+3] cyclization and TMSCl-promoted four-molecular cascade cyclization for the concise synthesis of highly functionalized spirooxindoles in excellent yields. Between them, the improved TMSCl-promoted cyclization reaction of… read more here.

Abstract: A facile synthetic approach to access of 3H-pyrrolo[2,3-c]quinoline derivatives has been achieved by a sequential I2-promoted cyclization/Staudinger/aza-Wittig/dehydroaromatization reaction. The targeted products were received in moderate to good yields (62–81%). The broad substrate scope and easy… read more here.
