Novel and efficient synthesis of 2-aminooxazoles from pyrimidin-2(1H)-one
Alifanov, Vadim L.,Babaev, Eugene V.
, p. 263 - 270 (2007/10/03)
Stepwise conversion of pyrimidin-2(1H)-one to 2-amino-5-aryloxazoles via oxazolo[3,2-a]pyrimidinium salts is reported. The sequence involves, (i) regioselective N-alkylation of pyrimidone by phenacyl bromides, (ii) cyclization of obtained 1-(2-aryl-2-oxoethyl)pyrimidin-2(1H)-ones into oxazolo[3,2-a] pyrimidinium salts under the action of fuming sulfuric (or triflic) acid, and (iii) reaction of the obtained salts with hydrazine leading to 2-amino-5-aryloxazoles.

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).
