2 , 2 ′‐Diketospirilloxanthin and 2,2 ′‐diketobacterioruberin have been prepared via the corresponding 15,15′‐dehydro compounds by condensation of 15,15′‐dehydroapo‐4,4′‐carotenedial (C 30 ) with 3‐methoxy‐(resp. 3‐hydroxy)‐3‐methyl‐ 2 ‐butanone. 2,2 ′‐Diketospirilloxanthin was identical with natural P 518.
