The Heck-oxyarylation reaction of deuterium labeled 2H-chromenes (12,15) has been studied whose synthesis was achieved in four steps starting from the readily available 7- benzyloxychromane (9). Since the deuterium label was not affected in the course of the oxyarylation, the formation of the neutral achiral intermediate 7 could be ruled out as a possible reaction pathway and a reason for the lack of enantioselectivity in asymmetric Heckoxyarylations. This also allowed the simple synthesis of 6a- and 11a-deutero-3- benzyloxypterocarpanes (13a,b).
