—— | methyl 4-bromo-2-(1,3-dioxoisoindolin-2-yl)-4-methylpentanoate | 140408-87-3 | C15H16BrNO4 | 354.2 |
Derivatives of α,β-methanovaline, α,β-methanophenylalanine and β-methyl-αβmethanoalanine have been prepared by regioselective side-chain functionalization of suitably protected amino acid derivatives, followed by cyclization with either sodium hydride or 1,8-diazabicyclo[5.4.O]undec-7-ene. The approach used in this work illustrates a method for the synthesis of cyclopropyl amino acid derivatives which is complementary to existing procedures.
