Endo-3,3-Dimethyl-4-oxobicyclo-[3.1.0]hexan-2-yl methane-sulfonate

Research output: Contribution to journalArticlepeer-review


The relative configuration of the endo isomer of the title compound, C HOS, has been established and the conformation of the diastereoisomer is discussed. The five-membered ring adopts an envelope conformation. The conformation of the methane-sulfonate substituent is stabilized by inter-molecular C - H⋯O hydrogen bonds. The crystal packing results in alternating layers of polar methane-sulfonates and stacked bicyclo-hexa-nyl rings parallel to ab.
