✦ Synopsis

2-Cyclopentenyl-and 2-cyclohexenylmethyl sulfoximines frameworks such as these can be found in many biologically active natural products. In addition to the methodological can be converted into angular carbon-functionalised, highly substituted, isomerically pure (ds Ն 98%) 2-oxabi-work, we report on studies towards the total synthesis of the euglobals G1 and G2 and arenaran A. cyclo[3.3.0]octanes and 2-oxabicyclo[3.4.0]nonanes in high yields by a convenient one-pot sequence. Molecular
