所有反应均在2 mL溶剂中用0.26 mmol的4a和0.20 mmol的2进行。CuBF 4= Cu(CH 3 CN)4 BF 4。孤立的产量。通过HPLC分析测定Ee。除非另有说明,否则反应在-20℃用2mL
甲苯中的0.26mmol 4和0.20mmol 2进行。孤立的产量。通过HPLC分析确定Ee。在0°C进行。图1.(1 R,3 R)-5b的X射线结构。提供了针对5a – r和化合物7的校正结构。某些化合物在光谱中的质子在2.60至2.70 ppm之间,这在实验详细信息部分中没有报告;请参见化合物5a,5d,5f,5g,5i和5o的最新1 H NMR报告。在实验详细信息部分中报告的1 H NMR峰少于化合物5b和5n的光谱。参见5b的更新的1 H NMR报告:7.88(d,J = 7.5 Hz)应替换为7.88(d,J = 7.5 Hz,1H);5n:7.44(d,J = 6.9 Hz,1H)应替换为7
