The borrowinghydrogen methodology (BH) has emerged as a powerful tool for the rapid construction of C–Cbonds, offering a greener alternative to traditional multi-step syntheses. This methodology involves the activation of inactivated alcohols followed by condensation or aldolization, ultimately leading to the regeneration of the saturated product. Herein, we report the C-alkylation of a hindered
The Ir(III)-catalyzed synthesis of 3-pyrrolidinols and 4-piperidinols combining 1,2,4-butanetriol or 1,3,5-pentanetriol with primary amines was carried out. This borrowinghydrogenmethodology was further extended to the sequential diamination of triols leading to amino-pyrrolidines and amino-piperidines.
