Copper‐Catalyzed Radical Silylarylation of Activated Alkenes: Preparation of β‐Silyl Amide‐Pharmaceutical Hybrids

Copper‐catalyzed silylarylation of N‐(arylsulfonyl)acrylamides via a tandem silyl radical addition/1,4‐aryl migration/desulfonylation sequence has been developed. This method employs silanes as the precursor of silyl radical and di‐tert‐butyl peroxide (DTBP) as the initiator. By using this cascade p...

Zusammenfassung:Copper‐catalyzed silylarylation of N‐(arylsulfonyl)acrylamides via a tandem silyl radical addition/1,4‐aryl migration/desulfonylation sequence has been developed. This method employs silanes as the precursor of silyl radical and di‐tert‐butyl peroxide (DTBP) as the initiator. By using this cascade procedure, a series of β‐silyl amide‐pharmaceutical hybrids which contain an α‐all‐carbon quaternary stereocenter were facilely synthesized.
