(Figure Presented) Enantioselective acyl transfer catalyst benzotetramisole (BTM) has been found to promote dynamic kinetic resolution of azlactones providing di(1-naphthyl)methyl esters of α-amino acids with up to 96% ee.

(Chemical Equation Presented) We report herein a trimethylsilyl chloride mediated substrate controlled 1,3-dipolar cycloaddition for the diastereoselective synthesis of either syn- or anti-imidazolines. This method provides scaffolds with four points of diversity and control over two stereocenters.

The reaction of molecular oxygen with several 2,4-disubstituted oxazolones (3a-3g) is studied in the present paper.It is shown that oxygen may induce oxidative dimerization to dehydrodimers (7a-7g) via the mesoionic form of the oxazolone.The equilibration
