Yield:29390-67-8 70% ，7585-39-9 30%
Reaction Conditions:
with ammonia in water at 60; for 5 h;Product distribution / selectivity;
Steps:
2
Compound 2 (3.0 g, 2.33 mmol) was dissolved in 50 ml concentrated NH4OH solution. The reaction mixture was stirred at 60° C. for 5 h, cooled to room temperature and poured into 500 ml acetone to give a white precipitate. TLC analysis performed on silica plates (EtOAc:2-propanol:conc. NH4OH:water-7:7:5:4) showed a mixture of product 4 (70%) and β-CD 1 (30%). The product 4 was recrystallized from ethanol-water (3:7). The 1H NMR data are as in Example 1.
