and efficient method for the synthesis of azabicyclo[4,3,0]nonanone and azabicyclo[5,3,0]decanone amino acid derivatives was developed with the palladium-catalyzed coupling of intermediates 9 and 10 with BocNH2 and Boc2NH and the following reduction of the C–C double bond by hydrogenation as the key steps. The exploration of the synthesis of C6-substituted dipeptide mimetics from 9 and 10 using Suzuki
