## Abstract The two regioisomeric 4‐diazo‐2,3,4,5‐tetrahydrofuran‐3‐ones **6** and **7** were prepared __via__ the common intermediate 2,3,4,5‐tetrahydro‐2,2‐dimethyl‐5,5‐diphenylfuran‐3‐one (**8**). Diazo transfer with 2,4,6‐triisopropylbenzenesulfonyl azide yielded **6**, whereas **7** was obtain

Structures of fundamental organic peroxides such as 1,2,4-trioxolanes , peracetic acid2, and dioxirane3 have been well established by microwave spectroscopy. 3,6-Dihydro-1,2-dioxins (1,4-endoperoxides) are also fascinating peroxides which are easily obtained by the reaction of 1,3-dienes with single
