Abstract
Abstract A new sequential two-step multicatalytic strategy is presented consisting in the efficient DBU-catalysed trichloroacetimidation of an alcohol followed by a ditriflylamine (Tf 2 NH)-catalysed intermolecular alkylation by silicon-based nucleophiles and C [BOND] H nucleophiles. The distinct feature of the trichloroacetimidate group allows use of weaker acid catalysts such as 1, 1′-bi-2-naphthol (BINOL)-derived phosphoric acid, pointing out the ...
