Versuchsvorschrift

In accordance with the process of Preparation 22, 5-benzyloxy-2-diazo-3-oxo-6-heptenoic acid methyl ester (1.16 g; 4 mmol) and copper acetylacetone complex (100 mg) were dissolved in 30 ml of anhydrous xylene. The reaction product was purified by silica gel column chromatography to obtain two types of isomers of 4-benzyloxy-2-oxo-bicyclo[3.1.0] hexane-1-carboxylic acid methyl ester (248mg) as an oily product.
