  Easy one-pot conversion of 2-chlorohydrazone into 2-oxohydrazone derivatives 2-azidohydrazone intermediates

  摘要：

  The simple, mild and selective conversion in good yields of 2-chlorohydrazone into 2-oxohydrazone derivatives is reported. The reaction easily occurs via 2-azidohydrazone intermediates and represents a convenient procedure for the useful transformation of the methylene into carbonyl group.

  chains at the 1- and 9-positions of dipyrromethanes was explored by using the hetero-Diels–Alder reaction of azoalkenes. New 5,5′-diethyldipyrromethanes and 5-phenyldipyrromethanes that were functionalized with open-chain hydrazone moieties, including derivatives with tetrazolyl groups, were prepared. Furthermore, the synthesis of new calix[4]pyrroles and bilanes was achieved by employing the bis(hetero-Diels–Alder)

• Functionalization of dipyrromethanes via hetero-Diels–Alder reaction with azo- and nitrosoalkenes

  5,5'-Diethyl- and 5-phenyldipyrromethanes participate in cycloadditions with azo- and nitrosoalkenes giving dipyrromethanes with side chains containing open chain oximes and hydrazones. By controlling reaction stoichiometry it is possible to get mono or 1,9-disubstituted derivatives. The reported methodology gave access to a range of dipyrromethanes with good structural features for various applications. It was demonstrated that reduction of dipyrromethanes containing alpha-oximino ester groups opens the way to new alpha-amino esters. (c) 2013 Elsevier Ltd. All rights reserved.
