The reaction of 1,3-bis-silyl enol ethers with 3-methoxalylchromones affords a great variety of functionalised 2,4'-dihydroxybenzophenones. These products are formed by a domino Michael/retro-Michael/Mukaiyama-aldol reaction. The synthesized compounds are promising candidates for the synthesis of the novel UV-A/B and UV-B filters.
1,3-双硅基烯醇醚与 3-甲酰基色酮反应可得到多种官能化的 2,4'-二羟基二苯甲酮。这些产物是通过多组分迈克尔/反迈克尔/Mukaiyama-aldol 反应形成的。所合成的化合物是新型 UVA/B 和 UVB 滤光剂合成的有前途的候选物。
