An approach to the title ring system starting with the available cinnamoyloximinoacetonitrile (1) is proposed. It involves its reaction with various nucleophiles and subsequent addition of the resulting pyrrole derivatives (3,4) to 2-substituted cinnamonitriles (5), in a Micheal type reaction, thus affording the pyrano[2,3-c]pyrroles (6).
