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 2-(Aryloxythio)benzoates by the First [3+3] Cyclizations of 3-Aryloxythio-1-silyloxybuta-1,3-dienes with 3-Alkoxy-2-en-1-ones
Functionalized 2-(aryloxythio)benzoates were regioselectively prepared by the first [3+3] cyclizations of 3-aryloxythio-1-trimethylsilyloxybuta-1,3-dienes with 3-alkoxy-2-en-1-ones. cyclizations - diaryl sulfides - regioselectivity - pyridines - silyl enol ethers
