Carbamate //- aiyl

When cysteine reacts with an alkyl or aiyl chloroformate, both the —SH and —NH groups are protected as a thiocarbonate and as a carbamate, respectively. Selective or simultaneous removal of the protective groups is possible. [Pg.299]

Other nickel-catalyst systems were also demonstrated to catalyse amina-tion of phenol derivatives, such as Ni(COD)2/SIPr-catalysed amination of aiyl carbamates, Ni(COD)2/dppf-catalysed amination of aryl sulfamates, and (dppf)Ni(o-tolyl)Cl-catalysed amination of aiyl sulfamates, mesylates, and triflates/ ... [Pg.428]

Ni-Catalysed Cross-coupling of iV-Aiyl Amides and Carbamates... [Pg.435]

Af-Aiyl amides can be catalytically activated in Ca yi-N or Cat-N cleavage manners depending on catalysts and reaction conditions. Ni(COD)2/IMes catalyses botylation of N-atyl amides with diboron reagents via Cat-N cleavage in the presence of NaOtBu. Ni(COD)2/PCy3 catalyses the reduction of iV-aiyl amides or iV-atyl carbamates with HBpin to afford Ar-H (Scheme 14.37). ... [Pg.435]
