상기 표 2에서 dl (%)/meso (%) 는 정제 수율(isolated yield)을 의미한다. 상기 표 2에서 보는 바와 같이 entry 6과 8의 경우 가장 좋은 수율을 나타냄을 알 수 있다. 이하에서는 entry 6을 Condition A로 하고, entry 8을 Condition B로 한다.
In Table 2, dl (%) / meso (%) means an isolated yield. As shown in Table 2, it can be seen that entry 6 and 8 show the best yields. Hereinafter, entry 6 is defined as Condition A, and entry 8 is defined as Condition B.
