Abstract: Herein we present the first example of transition metal-mediated stereodefined β-OH elimination, an atom economical [Cp*RhCl2]2-catalyzed SN2′-type coupling between easily available arenes and non-terminal tertiary 2-alkynylic alcohols at rt affording fully substituted allenes with H2O… read more here.

Abstract: 3-Spiropiperidino indolenines have been synthesized via novel Lewis acid-catalyzed SN2-type ring opening of activated aziridines with 1H-indoles followed by Pd-catalyzed dearomative spirocyclization with propargyl carbonates in up to 88% yields. The step and pot-economic transformation… read more here.
