A first total synthesis of thiamyxins A–C and E, an interesting group of natural products with antiviral activity and an acid-labile C2 exomethine position, is described. Overcoming the problem of inseparable diastereomers of the open-chain variants, thiamyxin C and E were obtained by opening the cyclic thiamyxins A and B.
