1.3 Conclusion<br />
In conclusion, I have reported the synthesis <strong>of</strong> substituted 2-(arylthio)benzoates and<br />
thioxanthones based on formal [3+3] cyclizations <strong>of</strong> 3-arylthio-1-trimethylsilyloxy-1,3-<br />
butadienes with 3-silyloxy-2-en-1-ones and 1,1-diacylcyclopropanes.
