Nonstabilized azomethine ylides are easily trapped by anthraquinone to form stable spiro-oxazolidines, which have an unusual ability to undergo a cycloreversion in the presence of other dipolarophiles at 120-150°C. All tested recycloadditions with carbonyl compounds and electron-poor alkenes occurred in moderate to high yields (41-92%). Moreover, increasing the reaction temperature to 210°C made it possible to obtain adducts with low reactive dipolarophiles.

Benzaldehydes react smoothly with nonstabilized azomethine ylides, generated in situ from sarcosine/formaldehyde or N-(methoxymethyl)-N- (trimethylsilylmethyl)benzylamine, to give 5-aryloxazolidines as intermediates. These were converted into 2-(alkylamino)-1-arylethanols in good yields by simple heating in methanol with hydrochloric acid, or by treatment with hydrazine hydrate in ethanol.
