Abstract |
Carotenoids are important natural products Which have medical, biological effect. We studied the synthesis of the natural carotenes using sulfone-mediated coupling reaction, protection of alcohol and double elimination. Recently, lycopene and lycophyll were efficiently produced by using Julia-Kocienski olefination, which can be obtained by the coupling the C10 geranyl benzothiazolyl(BT) sulfone with C20 crocetin dialdehyde.
The Julia-Kocienski olefination in the total synthesis of carotenoid natural products were demonstrated using the C5 BT-sulfone containing an acetal group, which was prepared as a chain-extension unit of Apocarotenoids. The double Julia-Kocienski olefination of the C5 BT-sulfone with C10 2,7-dimethyl-2,4,6-octatrienedial and deprotection of the resulting acetal groups efficiently produced C20 crocetin dialdehyde. Above protocol for apocarotenoid can be used the natural carotenoid and electronic conductivity of carotenoids.
