Synthesis of heterocyclic systems with a carbohydrate fragment
摘要:
The reactions of levoglucosenone with urea, thiourea and N-cyano- and N-nitroguanidines result in pyrimidine systems fused with a carbohydrate fragment. In all cases, the cyclization occurs stereospecifically. The structures of different products of conversion of levoglucosenone were established on the basis of NMR and X-ray diffraction data.
