The formation of product 10 can be explained by a domino ′Michael / retro-Michael / Mukaiyama-Aldol′ reaction. This type of reaction has been earlier reported for 1,3-bis(silyloxy)-1,3-butadienes. 29 26

Synthesis of 10: Reagents and conditions: i: Me3SiOTf (0.3 equiv) 20 °C, 10 min; ii: 1) 3a (1.3 equiv), CH2Cl2, 0 → 20 °C, 12 h; 2) HCl (10%). 1.3 Conclusion In conclusion, I have reported the synthesis of substituted 2-(arylthio)benzoates and thioxanthones based on formal [3+3] cyclizations of 3-arylthio-1-trimethylsilyloxy-1,3- butadienes with 3-silyloxy-2-en-1-ones and 1,1-diacylcyclopropanes.
