cohibin C (5S)-3-[(15RS,16RS,19Z)-15,16-dihydroxydotriacont-19-en-1-yl]-5-methylfuran-2(5H)-one 3-[(19Z)-15,16-dihydroxydotriacont-19-en-1-yl]-5-methyl-2,5-dihydrofuran-2-one 576.512 576.935 A member of the class of cohibins in which the long-chain dihydroxyalkyl group at position 3 is specified as 15,16-dihydroxydotriacont-19-en-1-yl. NB The absolute configuration of the stereocentre at position 5 on the furanone ring is known to be S, but only the relative configuration of the diol moiety has been assigned as threo. It has not yet been established whether it is the (R,R)-diol (as shown here) or the (S,S)-diol.
