Bacterial carotenoids. XLVIII. C50-Carotenoids. 16. Synthesis and chiroptical properties of the model compounds (2R, 6R, 2'R, 6'R)-2,2'-dimethyl-.epsilon.,.epsilon.-carotene and (2R, 6S, 2'R, 6'S)-2,2'-dimethyl-.epsilon.,.epsilon.-carotene. Andrewes, A. G.; Borch, G.; Liaaen-Jensen, S. (Norw. Inst. Technol., Univ. 6399-81-1 and 62430-55-1 which are cas registry numbers are also used here. Trondheim, Trondheim, Norway). Acta Chem. Scand., Ser. B, B30(3), 214-18 (English) 1976. CODEN: ACBOCV. DOCUMENT TYPE: Journal CA Section: 30 (Terpenoids) (2R,6S,2'R,6'S)-2,2'-Dimethyl-.epsilon.,.epsilon.-carotene (RXR) (2R,6R,2'R,6'R)-2,2'-dimethyl-.epsilon.,.epsilon.-carotene (R1XR1) were prepd. from the corresponding optically active irones (RCH:CHCOMe, R1CH:CHCOMe, resp.) and their NMR and CD properties reported. The abs. configuration (2R,6R,2'R,6'R) of the bacterial C50-carotenoid decaprenoxanthin (R2XR2) is based on these results. .
