Synthesis of medium-ring lactones via tandem methylenation/Claisen rearrangement of cyclic carbonates

Synthesis of medium-ring lactones via tandem methylenation/Claisen rearrangement of cyclic carbonates

Diğer sürümleri göster (1)

The conversion of vinyl-substituted 6- and 7-membered cyclic carbonates into 8- and 9-membered medium-ring lactones has been achieved in good yield using dimethyltitanocene in toluene at reflux. The reaction proceeds by initial formation of a ketene acetal which undergoes subsequent in situ Claisen...
