Description

Application

Zirconium (IV) chloride acts as an efficient Lewis acid catalyst for various reactions; such as:

• electrophilic addition reaction of indole with aldehydes/ketones to form bis(indolyl)methanes. electrophilic amination of activated arenes,
• transthioacetylization of acetals,
• deoxygenation of heterocyclic-N-oxides,
• reduction of nitro compounds,
• conversion of carbonyl compounds to 1,3-oxathiolanes,
• Biginelli reaction for the synthesis of 3,4-dihydropyrimidin-2(1H)-ones,
• direct amide coupling of non activated carboxylic acids and amines,
• synthesis of quinoxalines and pyrido[2,3-b]pyrazines,
• deprotection of t-butyldimethylsilyl (TBDMS) ethers.

Activates pyrrolidines for improved conversion, via a modified Bouveault reaction, to the corresponding α,α-dimethylamines.
