โฆ Synopsis
1,3-Dipolar cycloaddition reaction of carbonyl ylide with o-quinones afforded novel highly oxygenated spirocyclic compounds.

Carbonyl ylides react with tetraarylporphyrins to afford the corresponding [3+2] tetrahydrofuran cycloaddition products in moderate yields.
Treatment of various a-diazo ketones 1 and arylidenetetralones 2 in the presence of rhodium(II) acetate dimer leads to spiro-dioxa ring systems 3 as the only C O addition products with high regio-and chemoselectivity.
