| titleOfInvention | NEW OXAZOLIDINONE DERIVATIVES AND THEIR USE AS DUTIES IN LIQUID CRYSTAL MIXTURES |
| abstract | New chiral oxazolidin-2-one cpds. with a mesogenic side chain in the 3- or 4-position are of formula (IA) and (IB): where "star" = a chiral centre; (star) = opt. a chiral centre; R1 = opt. branched 1-16C alkyl or 3-16C alkenyl, opt. contg. asymmetrical C atoms, in which one or more non-adjacent -CH2- gps. may be replaced by -O-, -S-, -CO-, -O-CO- and/or -CO-O and one or more H may be replaced by F, Cl, Br or CN; R1-3 R2-3 = H, 1-12C alkyl (in which one -CH2- gp. may be replaced by -O- or -S- and the terminal CH3 gp. may be replaced by CH2OR4, CH2SR4 or CH2CONH2), phenyl or cyclohexyl (opt. substd. by ORT4, F or I); R4 = 1-10C alkyl; j, l and n = O, 1 or 2; k and m = O or 1; k = O if j and/or 1 = O; m = O if n = O, K + 1 + n = 1,2 or 3; A1-3 = phenyl, cyclohexyl, pyrimidin-5-yl,pyrimidin-2-yl, pyrid-2-yl, pyrid-3-yl, pyridazin-3-yl; and A1-2 = also pyazin-2-yl, 1,3,4-thiadiazol-2-yl, 1,3-dioxan-2-yl, 1,3-dioxan-5-yl, 1,3-dithian-2-yl, 1,3-dithian-5-yl, thiazol-5-yl, thien-2-yl, piperazin-2-piperazin-1-yl or thiazol-2-yl; M1-2 = -CO-O-, -O-CO-, -CH2CH2-, -CH=CH-, -CH2O- or -OCH2-; X = -O-CH2-, -CH2-, -CO-O-, -O-CO-, -CH2-O- or -C2H4-. They are prepd. by multistage synthesis, using standard techniques described in the literature. |
