## Abstract The 1,3โ€dipolar cycloaddition of arylnitriloxides on 1,2โ€dihydroisoquinoline derivatives led to new 3โ€aryl, 3aโ€8,9,9aโ€tetrahydro[5,4โ€__c__]โ€isoxazoloisoquinoline adducts. The regioselectivity of the cycloaddition reactions is discussed on the basis of ^1^H and ^13^C NMR data.

Influence of a 2-Fluoro Substituent on Diastereoselectivity in the 1,3-Dipolar Cycloadditions of Nitrones. -2-Fluoro nitrones, e.g. (IIIa)-(IIIc), show reverse diastereoselectivity in the title reaction compared with 2-hydro nitrones such as (IIId)-(IIIf). It is noteworthy that no appropriate catal
