Naturally occurring antrocamphin A (1) is a potent anti-inflammatory compound from the edible fungus Antrodia camphorata (Taiwanofungus camphoratus), whose wild fruiting body is used as a valuable folk medicine in Taiwan. This study is the first total synthesis of antrocamphin A (1) and its analogs. Their inhibition ability on NO release, superoxide anion generation, elastase release and platelet aggregation are reported herein.

(1) or (2) and aryl bromide partners. The inclusion of aryl iodide instead of aryl bromide with the same organostannanes, significantly improves the efficiency of the coupling, providing a variety of desired products in good to excellent yield. The yields of Stille coupling are compared to the different reactivity of arylhalides. This study of Stille coupling with different arylhalides are documented

Stille (arylstannane) conditions used Pd-0-mediated cross-coupling reactions for preparation of thiophene/aryl analogs. Different arylhalides were compared when coupled with heterometal (thiophenestannane) system. Comparable yields have now been obtained by Stille (arylstannane) couplings with different reactivity of arylhalides.
