Spiro-fused indanones were constructed using a [4 + 2]-cycloaddition approach from a-methylene indanone dienophiles, which were elaborated from 4-chromanone in a number of steps including a key rearrangement process. This type of spiro-fused structure forms the central core ring system found in natu

Reaction of diazoketodiester 11 with methyl glyoxylate in toluene in the presence of catalytic rhodium(II) acetate gives predominantly the 6,8-dioxabicyclo[3.2.1]octane 13. Acid-catalysed rearrangement of the corresponding alcohol 14 favours at equilibrium the 2,8-dioxabicyclo[3.2.1]octane skeleton
