The mild and efficient generation of benzenesulfenic acid by the thermolysis of ethyl 2- ethoxycarbonyl-3-(phenylsulfinyl) butanoate 8 in refluxing dichloromethane, and its in situ trapping with (E)-and (Z)-1-methoxybut-2-en-3-yne to form (E)-1-methoxy-3-(phenylsulfinyl) buta-1, 3-diene 10 and (Z)-1-methoxy-3-(phenylsulfinyl) buta-1, 3-dienes 11 respectively proceeds in high yield. The lithium perchlorate catalysed Diels–Alder reaction of 10 with ...
