Application
1. It's used as a pharmaceutical intermediate. The ring (sub) isopropyl malonate can be used as an intermediate in pharmaceutical synthesis, and it can be used to prepare the compound 3-oxo-4-phenylvalerate Ethyl, further preparation of 3, 4-disubstituted-6-phenylethylpyridinone HIV-1 reverse transcriptase inhibitors.
2. It's used in organic synthesis.The protective reagent is obtained by aldol condensation and reduction with triethylamine formaldehyde. the benzyl substituted michele acid is hydrolyzed, lost CO2 and chlorosulfonic acid for Friedel-Crafts cyclization to produce 2, 3-dihydro-2-indanone. Accelerate the Noven Gall concentration reaction between aldehyde and Michaelis acid in ionic liquid (Knoevenagel condensations).
