Buchwald hartwig coupling microwave

WebIn this thesis, a synthesis toward analogues of Clausenalansine A has been investigated. At first, 4-bromophenol was protected with the tert-butyldiphenylsilyl protecting group. The resulting (4-bromophenoxy) (tert-butyl)diphenylsilane (1) was then coupled with 3- methoxyaniline (2) in a Buchwald- Hartwig amination reaction. WebDescription Application This second-generation kit contains the reagents, catalyst, and solvent required to perform a Buchwald-Hartwig reaction in TPGS-750-M, a surfactant developed by the Lipshutz group as a greener alternative to organic solvents.
