Functionalized 5‐(arylselanyl)‐2‐(arylsulfanyl)benzoates were prepared by [3+3] cyclocondensation of 3‐(arylsulfanyl)‐1‐(silyloxy)buta‐1,3‐dienes with 2‐(arylselanyl)‐3‐(silyloxy)‐alk‐2‐en‐1‐ones.
Regioselective Synthesis of 4-(Arylsulfanyl)-2-hydroxyhomophthalates by [4+2] Cycloaddition of 3-(Arylsulfanyl)-1-(trimethylsilyloxy)buta-1,3-dienes with Dimethyl Penta-2,3-dienedioate
The [4+2] cycloaddition of 3‐(arylsulfanyl)‐1‐(trimethylsilyloxy)buta‐1,3‐dienes with dimethyl penta‐2,3‐dienedioate provides a convenient and regioselective approach to a variety of 4‐(arylsulfanyl)‐2‐hydroxyhomophthalates.
