The diastereomeric product ratios from reactions involving the addition of various reagents to the carbonyl of φCH3HC-COR compounds varies over a wide range. This variation is interpreted as due partly to changes in the structure of the diastereomeric transition states with changes in the size of R. For example, when R is smaller than the φCH3HC group the diastereomeric product ratios are close to
从包括添加各种试剂的至φCH的羰基反应的非对映体产品比率3 HC-COR的化合物而变化在大范围内。这种变化被解释为部分由于变化的非对映体的过渡态的结构与R的大小例如变化,当R大于φCH较小3 HC组非对映体产物的比率接近那些在假设预测即1和2是最小能量非对映体的过渡态; 以及当R大于φCH更大3 HC基,非对映体产物的比率是大的,更接近那些人们可能预期,如果5和6 是最小的能量跃迁状态。
