Regioselective Synthesis of 5-(Arylsulfanyl)- and 5-(Benzylsulfanyl)-6-phenylsalicylates by One-Pot Cyclizations of 1,3-Bis(silyloxy)buta-1,3-dienes with 2-(Arylsulfanyl)- and 5-(Benzylsulfanyl)-3-ethoxy-1-phenylprop-2-en-1-ones
5‐(Arylsulfanyl)‐6‐phenylsalicylates were prepared by one‐pot cyclizations of 1,3‐bis(trimethylsilyloxy)buta‐1,3‐dienes with 2‐(arylsulfanyl)‐3‐ethoxy‐1‐phenylprop‐2‐en‐1‐ones.
