Synthesis of Methyl 2-arylthio-5 -aryldiazenylbenzoates by Formal [3+3]Cyclizations of 3-arylthio-1-silyloxy-1,3-butadienes with 2-aryldiazenyl-3-silyloxy-2-en-1-ones
摘要:
The formal [3+3]cyclization of 3-arylthio-1-silyloxy-1,3-butadienes with 2-aryldiazenyl-3-silyloxy-2-en-1-ones afforded a variety of 2-arylthio-5-aryldiazenylbenzoates.
Regioselective synthesis of functionalized 2-(phenylthio)benzoates by ‘[3+3] cyclization/homo-Michael’ reactions of 1-methoxy-1-trimethylsilyloxy-3-phenylthio-1,3-butadienes with 1,1-diacylcyclopropanes
