The first chemical cyclization of tetradepsipeptides such as 1, which contain only building blocks with the same configuration and without N-methyl groups, has been achieved with the new, activatable 2,4-(MeS)2C6H4[BOND]O[BOND]CO (Bmpc) protecting group. The initially formed cyclic mixed anhydride spontaneously eliminates CO2 to give 2.
