摘要:A process for the synthesis of lipid cations having general formula (6): n n nin which: R 1 represents a lipophilic chain; R 2 , R 3 , R 4 , which are identical or different from one another, represent C 1 -C 10 alkyl, C 1 -C 10 alkenyl, or C 1 -C 10 alkynyl radicals, optionally containing hydroxyl, ether, halogen and acyloxy functions, and X − is an oxy-anion or a halide; in which a compound of formula (2), n n nin which R 5 and R 6 , which are identical or different from one another, represent a C 1 -C 5 acyl, a benzyl group or a diol-protective group, is reacted in an alcoholic solvent with from 1 to 6 equivalents of NR 2 R 3 R 4 .

摘要:The present invention relates to a process for the stereo-specific synthesis of indole derivatives of formula: ##STR1## which consists in using 3-tosyloxy-1,2-O-isopropylidenepropane-1,2-diol (II) in an optically pure form in order to introduce the asymetric carbon C* of compound (I). Compound (II) is condensed with a suitable primary amine in order to prepare an oxazolidinone and condensation with a suitable phenol, and the oxazolidinone ring is then opened to form an indole compound (I).

摘要:The present teachings relate to a composition comprising a functionalised dye and a diallylamine comonomer, and the use of such compositions in methods of colouring a substrate. The present teachings provide improved bonding of a dye to a substrate, and preferably allow colouring to be conducted entirely in the presence of an aqueous solvent.
