## Abstract **(βˆ’)‐Dysibetaine has been synthesized** in 11 steps from readily available L‐malic acid (see scheme). The key step is a unique Ugi 4‐center‐3‐component cyclization reaction, where an ester group acts as the carboxylic acid component. The use of 1,1,1,3,3,3‐hexamethyldisilazane as an am
