A series of N-(tosylmethyl)carbodiimides (TosCH2N=C=NR1, 3) have been prepared from the corresponding thioureas.Carbodiimides 3 with R1 = triphenylmethyl or tert-butyl are useful synthons in a new one-step synthesis of 2-(alkylamino)-1,3-oxazoles 10 from aromatic aldehydes.Acid-induced removal of the triphenylmethyl group from 10 gives 2-amino-1,3-oxazoles (11).
