Syn‐gled out: The syn diastereo‐ and enantioselective addition of azlactones to 3‐vinylindoles was accomplished by using a chiral, binapthol‐derived, Brønstedacid catalyst (see scheme). This method enables facileaccess to tryptophanderivatives with adjacent quaternary and tertiary stereogenic centers, which are potentially useful for the synthesis of peptidomimetics.
