A beta-alanine derivative of the formula (I) wherein R
1
is hydrogen atom or an amino protective group; A is a lower alkylene group or a lower alkenylene group; R
2
is hydrogen atom or an amino group which may be substituted with an acyl group; R
3
is hydrogen atom or an aryl or aralkyl group which may be substituted with one or more of hydroxy and/or lower alkoxy, a moiety represented by the formula (II), which is a bivalent N-containing 6- to 8-membered heterocyclic group, or a pharmaceutically acceptable salt thereof.

its application to oxidative cross-couplings of aromatics via decarboxylative/C–H or double decarboxylative activations that use I2 as the terminal oxidant. This strategy allows the preparation of biaryls previously inaccessible via decarboxylative methods and holds other advantages over existing decarboxylative oxidative couplings, as stoichiometric transition metals are avoided.
