present interesting potential as synthetic intermediates and as unusual motifs for incorporation into biologically active compounds. Here, an efficient synthesis of functionalized 1,4-dioxenes is achieved in two steps. Using keto-diazo compounds, a ruthenium catalyzed O–H insertion with β-halohydrins followed by treatment with base results in cyclization with excellent selectivity, through O-alkylation
