diacetals using 2,3-butane dione. These diacetals are extremely robust and can be further chemically diversified and resolved with chirality embedded in the 1,4-dioxane ring attached to the aromatic back bone as a result of the anomeric effect. These systems can serve as ligands, auxiliaries or organocatalysts for asymmetric synthesis.
1,3-二羟基苯已被2,3-丁烷二酮保护为环状二缩醛。这些二缩醛非常结实,由于异头作用,其手性可嵌入与芳香族背骨相连的1,4-二恶烷环中,并且可以进一步化学多样化和拆分。这些体系可以用作不对称合成的配体,助剂或有机催化剂。
