A novel method for the RuII-catalyzed regioselective synthesis of highly functionalized furans from readily available cyclic and acyclic diazodicarbonyl compounds and terminal alkynes is described. The devised protocol offers a straightforward means to the construction of a variety of diverse furan derivatives through powerful cascade processes, including the formation of ruthenium carbenoid, cyclopropenation

novel and readily available method for synthesis of pyrroles possessing substituents with various functional groups has been developed, by means of thermal iminocyclopropene rearrangements. It will provide a novel and readily available access to pyrroles under mild reaction conditions with simple procedures. The regioselectivity in this iminocyclopropene rearrangement was disclosed.
