詳細

アプリケーション

Butylboronic acid N,N,N′,N′-tetramethyl-D-tartaric acid diamide is a dioxaborolane ligand that can be used to prepare:

• Enantioenriched spiropentanes via zinc catalyzed cyclopropanation of corresponding hydroxymethylallenes.
• 1,2,3-trisubstituted cyclopropane derivatives by asymmetric cyclopropanation of allylic alcohols in the presence of zinc reagents.
• Glycolipids plakosides A, B, and their derivatives by Sharpless asymmetric dihydroxylation and cyclopropanation reaction.
