Sc(OTf)(3) effectively catalyzes the condensation of 2-alkyl-N-tosylaziridine with a wide variety of aldehydes and ketones, producing 5-alkyl-1,3-oxazolidines in good yields and excellent regioselectivity at catalyst loadings as low as 1 mol%.
We present herein the results of microwave promoted N-alkylations of isatin (1)with different alkyl, benzyl and functionalized alkyl halides. Reactions were carried out under different conditions, always employing methodologies compatible with MW assisted chemistry. Generation of isatin anion employing diverse bases and solvents or using the preformed isatin sodium salt was tested. The best res...
