利用共軛酯類與α、β-不飽和醛類藉由不對稱有機催化試劑進行double-Micahel 反應建構出多取代之六員環衍生物,再藉由自由基環化反應或Pictet-Spengler反應建構出具有吲哚的化合物,而且具有高鏡像選擇性,也利用X-ray單晶繞射分析決定出其絕對立體組態。
Asymmetric synthesis of highly functionalized compounds were achieved by a sequential organocatalyzed double Michael reaction of conjugated esters and α,β - unsaturated aldehydes, and radical cyclization or Pictet-Spengler reaction with high enantioselectivities and modrate diastereoselectivities. The absolute stereochemistry of major diastereomer was determined by X-ray analysis.
