## 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

## Abstract Substituted 4,5‐dihydro‐3‐methylene‐2(3__H__)‐furanones 1 react as dipolarophiles with diphenylnitrilimine to give the corresponding spiro[furan‐pyrazolin]ones 2. From the compound 1a, 1,3‐diphenyl‐7‐oxa‐1,2‐diazaspiro[4,4]non‐2‐en‐6‐one (2a) is formed. In the other cases, a primarily f
