  Trapping of a phosphazide intermediate in the Staudinger reaction of tertiary phosphines with azides and its application to the synthesis of analogs of the marine alkaloid midpacamide

  摘要：

  A new method based on the reaction of an E-phosphazide, ail intermediate in the Staudinger reaction between triphenylphosphine with an azide, with heterocumulenes allows the one-pot, two-component synthesis of a number of analogs of the pyrrole-imidazole marine alkaloid midpacamide. The procedure, which involves sequential treatment of the appropriate alpha-azido ester with triphenylphosphine and isothiocyanate leads to the thiohydantoin product after aqueous workup. The cyclization conditions call also be adapted to the synthesis of hydantoins by using isocyanates. (C) 2004 Elsevier Ltd. All rights reserved.

  An iminophosphorane-based approach for the synthesis of spiropyrrolidine–imidazole derivatives

  摘要：

  A method based on the reaction of an E-phosphazide, an intermediate in the Staudinger reaction between triphenylphosphine and an azide, with heterocumulenes allows the one-pot, two-component synthesis of a number of pyrrole-imidazole derivatives. The procedure, which involves sequential treatment of the appropriate a-azido ester with triphenylphosphine and isocyanate leads to the hydantoin product after aqueous work-up. The cyclization conditions can also be adapted for the synthesis of thiohydantoins by using isothiocyanates. These hybrids pyrrole-thiohydantoins undergo a novel oxidative spirocyclization by action of DDQ to give a tricyclic derivative (pyrrole-pyrrolidine-imidazole), which displays an interesting cytotoxic activity.

  A two-step synthesis of the N-acylated alpha -azido-omega -aminovalerate. a common intermediate for the synthesis of midpacamide and dispacamide, is described. This intermediate undergoes cyclization through the corresponding alpha -ureido ester derivative to give the 3-methylhydantoin ring present in midpacamide, whereas the reaction with triphenylphosphine. tosyl isocyanate and ammonia followed by cyclization of the resulting guanidine derivative provides the 2-aminoimidazole ring present in dispacamide.
