说明

應用

已证实 VANOL 是用于催化型不对称 Diels-Alder 反应、亚胺羟醛反应以及氮杂环丙化反应的绝佳配体。

(R)-VANOL is a vaulted biaryl ligand that may be used in the following processes:

• Transformation of 3-substituted cyclobutanones to enantiopure γ-butyrolactones via asymmetric Baeyer-Villiger Reaction in the presence of an aluminum catalyst.
• Asymmetric aziridination of N-(4-(Methylsulfonyl)benzylidene)diphenylmethanamine to form (2S,3S)-ethyl 1-benzhydryl-3-(4-(methylsulfonyl)phenyl) aziridine-2-carboxylate.
• Conjugate addition of terminal alkynes to 2-arylidene-1,3-diketones with high enantioselectivity in the presence of diethyl zinc.
