ABSTRACT:
A modified solid-support for use as a supported reagent for use in reduction reactions, including reductive amination comprising a solid-support having an tetrasubstituted ammonium cation species ionically bonded to a borohydride anion species extending therefrom having the general formula:whereinP is a solid-support, S is a spacer group selected from the group consisting of alkylene, {including —(CH2)n—}, alkyleneoxy {including -0(CH2)n—}, alkylenethio {including —S(CH2)n—} and alkylenecarboxy, {including —O(O)C—(CH2)n—}, n=2-16. R1, R2, R3and R are each independently selected from the group consisting of alkyl, cycloalkyl, haloalkyl and aryl. Y equals 1, 2 or 3. H is hydrogen or deuterium.
