说明

應用

Triethyl orthoacetate is a general reagent used to functionalize alcohols with acetate groups. It can be used in following reactions:

• Stereocontrolled total synthesis of a naturally occuring indole alkaloid, (−)-aspidophytine.
• Conversion of allylic alcohols to γ,δ-unsaturated esters under mild acidic condition, a reaction popularly known as Johnson–Claisen rearrangement.
• Synthesis of heterocycles such as 2-oxazolines and quinazolin-4(3H)-one derivatives.
