A series of vulpinicacids differing by the aryl or heteroaryl groups placed in the ester α-position were prepared by Suzuki–Miyaura cross-coupling involving a common iodide and the corresponding aryl boronates. The preparation of the iodide precursor from (+)-dimethyl l-tartrate required four steps: the esterification of one hydroxyl group, a Dieckmann cyclization allowing the construction of the
