The Front Cover shows a traditional Chinese style painting which presents a panda eating bamboo. The bamboo represents the oxygen atom from the N ‐oxide where plum blossom represents another oxygen atom. We demonstrated only one of the two carbonyl oxygen atoms in these intermediates selectively cyclizes to the polysubstituted oxazoles in acidic conditions. The panda selects the bamboo, which symbolizes the control of selectivity in this reaction. The authors acknowledge the artist, Yiyun Hu for graphical support (born in Chang Sha, Hu Nan Province, People's Republic of China). More information can be found in the Communication by A. S. K.
