． 但该方法不适用于2-取代苯基硫代黄酮的合成。噻吩与α，β-不饱和酸在高温下直接缩合，得到低至中等产率的硫代铬-4- 1，并产生相应的二硫化物和烯醇硫醚等副产物。
. However, this method isnot suitable for the synthesis of thioflavanones with 2-substituted phenyl groups. The direct condensation ofthiophenol with α,β-unsaturated acids proceeds at hightemperature to give thiochroman-4-ones in low to moderateyields with side products such as the corresponding di-sulfides and enol thioethers.
