Abstract

Curcumin and demethoxycurcumin were synthesized via an isoxazole-masking strategy. A 3,5-disubstituted isoxazole, obtained by [3 + 2] cycloaddition of a nitrile oxide and an alkyne, underwent mild reductive N-O cleavage to reveal the β-diketone core in good yield.

异恶唑策略合成姜黄素和去甲氧基姜黄素

采用异恶唑掩蔽策略合成了姜黄素和去甲氧基姜黄素。一个3,5-二取代异恶唑是由一个氧化腈和一个炔[3 + 2]环加成得到的，经过温和的还原性N-O裂解，以良好的收率显示出β-二酮核心。
