## Abstract Benzonitrile oxide cycloadds to the CC bond of substituted 4,5‐dihydro‐3‐methylene‐2(3__H__)‐furanones 1a–1g. Thus, (__E__)‐1a and (__E__)‐1b are converted into the corresponding isoxazolinespirodihydrofuranones (4__RS__,5__RS__)‐2a and (4__RS__,5__RS__)‐2b, and (__E__)‐1c is converted
