The synthesis of oxazolines using electrophilic cyclization of allylic amide is a simple and powerful method. However, cyclization involving arylsulfenylation requires harsh reaction conditions. We found that the reaction proceeds under mild heating

A revised structure for trichodermatide A, which is a C10 epimer of the originally reported structure, is proposed. The revision is supported by the X-ray structure of a synthetic intermediate synthesized according to our previous route for trichoder
