THE STUDIES OF METAL ION CATALYZED CARBON-HYDROGEN INSERTION OF α-ALKOXY-α'-DIAZOKETONES DERIVED FROM MANDELIC AND LACTIC ACIDS
The cupric acetylacetonate is the best catalyst to induce the carbon-hydrogen inserted reaction for the α-alkoxy-α'-diazoketones derivatives (5 and 6).The side reactions such as aromatic carbon-hydrogen insertion and rearrangement could be prevented.

Rhodium Acetate Catalyzes the Addition of Carbenoids α- to Ether Oxygens
Diazo-carbonyl compounds, when catalyzed by rhodium acetate, insert preferentially adjacent to ether oxygens.This phenomenon was exploited to develop a synthesis of 3(2H)-furanones.

A CONDENSED SYNTHESIS OF DIHYDRO-3(2H)-FURANONE
A straight forward synthesis of dihydro-3(2H)-furanone is described.An attempted preparation of the oxetan-3-one precursor 10 by this method gave, instead, the ring enlargement product 11.
