corresponding isoxazolidines. In the case of aldonitrones reactions proceed giving the diastereomeric mixtures. The ratio of isomers is changing during the reaction process due to the reversibility of the cycloaddition reaction. The cytotoxic and virus-inhibiting activity against influenza virus was investigated for selected adducts. Graphical Abstract

The preparation and potential anti-inflammatory activity of a series of novel substitutedspiro[isoxazolidine-3,2'-tricyclo[3.3.1.1(3,7)]decanes] (7, 11-30) are reported. The synthesis of the title compounds was accomplished via a 1,3-dipolar cycloaddition reaction of nitrones with appropriate olefins.

Adamantanone-derived nitrone 4 and some other keto-nitrones, when reacted with aromatic and aliphatic aldehydes in refluxing toluene or tetrahydrofuran, formed the corresponding aldonitrones (Z)-10, the latter arising from the fragmentation of an initially formed 1,4,2-dioxazolidine 6 to adamantan-2-one and an oxaziridine intermediate 11, which then rearranges to (Z)-10.

Reaction of chlorosulfonyl isocyanate (CSI) with nitrones (derived from cyclic conjugated ketones), - and 3,4-dihydro-2H-pyrrole-1-oxides, -,-has been studied. Nitrones, -, react with CSI to form the enamidea, , -, and the cyclil-amide, , in yields ranging from 33 to 72 %. However, the 5,4-dihydro-2H-pyrrole-1-oxides, -, on reaction with CSI gave the 2H-pyrr-oles, -, in good yields. The 3,4-dihydr
