Synthesis of amino acids with isolated saturated (hetero)carbocyclic scaffold was disclosed. The method relied on Suzuki cross-coupling reaction of heteroacycloalkene triflates and N-Boc-tetrahydropyridine boron pinacolates followed by catalytic hydrogenation of the conjugated dienes thus obtained, which proceeded with good diastereoselectivity for scaffolds with two six-membered cycles and low diastereoselectivity for a five-membered analog. Several amino acid derivatives have also been obtained, i.e. amino esters, NH- and N-Boc-substituted amino acids – promising building blocks for medicinal and synthetic chemistry.
