[Problem] To provide novel compounds that are S1P1 receptor agonists and exhibit an immunosuppressive activities by inducing lymphocyte sequestration in secondary lymphoid tissues. In addition, to provide a pharmaceutical agent which comprises the compounds as an effective component, in particular to provide a therapeutic and/or prophylactic agent for an autoimmune disease and the like.
[Solving Means] Amino acid compounds that are represented by the following Formula (1) are provided
Direct carboxylation of simple arenes under atmospheric pressure of CO2 is achieved through a rhodium-catalyzedC-Hbondactivation without the assistance of a directinggroup. Various arenes such as benzene, toluene, xylene, electron-rich or electron-deficient benzene derivatives, and heteroaromatics are directly carboxylated with high TONs.
