Title
(EN) C-15 PHOSPHONATE REAGENT FOR PREPARING CANTHAXANTHIN
(FR) REACTIF DE PHOSPHONATE C-15 POUR PREPARER LA CANTAXANTINE
Abstract
(EN)
The present invention describes novel C-15 allenic phosphonate reagent compositions of formula (8) wherein R and R' = C1 - C4 alkyl groups or R, R' = (CH2)n (n = 2 or 3). The invention also describes novel C-15 allylic phosphonate reagent compositions of formula (9) wherein R and R' = C1-C4 alkyl groups. The invention also describes methods of preparing canthaxanthin, the phosphonate reagent compositions, and a tertiary propargylic alcohol of formula (7).
