Ozonolysis of 2-methyl-1H-indene (1) afforded the stable secondary ozonide 1,4-epoxy-4-methyl-1H,4H-2,3-benzodioxepin (2). This compound crystallizes in two polymorphic forms, depending on the solvent used. The monoclinic form 2a containing two symmetry-independent molecules (enantiomers) is obtained by crystallization from dichloromethane. In contrast, the orthorhombic modification 2b is obtained from ethyl acetate solution and crystallizes as a conglomerate of enantiomerically pure single crystals. Additionally, the ring-opened product 2-(2-oxopropyl)benzoic acid (3) was obtained and investigated by X-ray crystal structure analysis.

A novel selective fragmentation of cycloalkanones by NaNO2/HCl has been established. The C-C bond cleavage reaction proceeds smoothly under mild conditions, selectively affording versatile keto acids or oxime acids. The methodology can streamline the synthesis of valuable chiral molecules and isocoumarins from readily available feedstocks.
