Abstract

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.
