4H-PYRAN-4-ONE C화학적 특성, 용도, 생산
용도
4H-Pyran-4-one was used in the synthesis of probes grafted on the lipid headgroups.제조 방법
1) from Diethylacetone dioxalate by cyclization to Chelidonic acid (gamma-Pyrone- 2,6-dicarboxylic acid). The acid yields 4H-Pyran-4-one by decarboxylation.2) by heating of I-Methoxypent-l -en-3-yn-5- al diethylacetal with Methanol and water, using Mercuric sulfate or Sulfuric acid catalyst.
정의
