  Synthesis of steroid–ferrocene conjugates of steroidal 17-carboxamides via a palladium-catalyzed aminocarbonylation – Copper-catalyzed azide–alkyne cycloaddition reaction sequence

  摘要：

  Steroids with the 17-iodo-16-ene functionality were converted to ferrocene labeled steroidal 17-carboxamides via a two step reaction sequence. The first step involved the palladium-catalyzed aminocarbonylation of the alkenyl iodides with prop-2-yn-1-amine as the nucleophile in the presence of the Pd(OAc)(2)/ PPh(3) catalyst system. In the second step, the product N-(prop-2-ynyl)-carboxamides underwent a facile azide-alkyne cycloaddition with ferrocenyl azides in the presence of CuSO(4)/sodium ascorbate to produce the steroid ferrocene conjugates. The new compounds were obtained in good yield and were characterized by (1)H and (13)C NMR, IR. MS and elemental analysis. (C) 2011 Elsevier Inc. All rights reserved.

  on the structure of the acyl azides, consecutive hydrolysis toward corresponding primary amides was observed. ‘Direct’ aminocarbonylation of the same iodoalkenes was also carried out by using ammonium carbamate as ammonia source under mild conditions. The α,β-unsaturated primary amides, formed in a chemoselective reaction, were isolated in good to excellent yields.

  A new method for the synthesis of primary amides from alkenyl iodides in one carbonylation step using ammonium carbamate as ammonia synthon is reported. The products were obtained in good yields under mild reaction conditions using CO (1-6 bar). Steroidal substrates with various moieties (e.g., 6-OH group, lactams, or aromatic A-ring) could be converted selectively into the products.
