## Abstract Alkylation of 4,4,6‐trimethyl‐2‐cyclohexenone (**1**) in toluene in the presence of sodium bis(trimethylsilyl)amide proceeds smoothly to give high yields of compounds **2**. Irradiation (λ= 366 nm) of the 6‐allyl‐4,4,6‐trimethyl‐2‐cyclohexenones **2a–c** yields mixtures of the isomeric
The title compound, C 8 H 9 NO 5 , was prepared as a by-product in synthetic efforts to prepare a carbasugar analogue of a putative intermediate, viz. (AE)-6-hydroxymethyl-7-oxabicyclo[2.2.1]hept-2-exo-3-endo-diol, in the uridine diphosphate-galactopyranose mutase-catalysed reaction. The structure s
