Abstract

A series of borylated conjugated trienes and skipped dienes is prepared by Ru-catalysed cross-dimerisation using alkynyl-, dienyl-, and vinyl boronates. These products are used as synthetic building blocks for polyene substructures by subsequent Pd-catalysed cross-coupling in a one-pot vessel without deprotection.
