| titleOfInvention | Substituted oxazolidines and tetrahydro-oxazines |
| abstract | Heterocyclic compounds having the general formula: <FORM:0869129/IV (a)/1> in which R is a C1-C6 alkyl group or an aralkyl group containing not more than 8 carbon atoms, R1 is hydrogen or a C1-C6 alkyl group, R11 is hydrogen or a C1-C6 alkyl or alkenyl group and n is 2 or 3, may be polymerized or co-polymerized with other polymerizable monomers. For example, when catalysed with a small amount of peroxide these heterocyclic compounds give adhesive polymers at room temperature and brittle solids when heated at 125 DEG C. for 24 hours. In addition, hydroxylated molecules, such as those of water, methanol or ethanol undergo addition reactions with these compounds to produce polymers.ALSO:The invention comprises new substituted oxazolidines and tetrahydro-oxazines of formula: <FORM:0869129/IV (b)/1> in which R is a lower alkyl or aralkyl group; R1 is a hydrogen atom or a lower alkyl group; R11 is a hydrogen atom of a lower alkyl or alkenyl group; and n is 2 or 3. The "lower" alkyl and alkenyl groups contain not more than 6 carbon atoms and the "lower" aralkyl groups not more than 8 carbon atoms. They may be prepared by refluxing an N-substituted-N-alkynyl-o -aminoalkanol of formula: <FORM:0869129/IV (b)/2> in the presence of an inert organic solvent and a catalytic amount of potassium hydroxide for a period from a few minutes to 4 hours at a temperature of 110-145 DEG C. The unreacted constituents are removed from the reaction mixture and the desired product distilled from the remaining mixture. Suitable solvents are, for example, p-xylene and toluene. The products may be catalytically hydrogenated to give the corresponding compounds with a saturated side-chain -CH2CH2R11 and these are identical with compounds obtained by reacting an N-substituted-2-aminoethanol or an N-substituted -3-amino-1-propanol with the appropriate aldehyde or ketone as follows:- <FORM:0869129/IV (b)/3> Examples are given of the preparation of compounds in which R is benzyl, isopropyl, or isobutyl; R1 is hydrogen, ethyl or n-propyl; R11 is hydrogen, n-butyl or isopropenyl; and n is 2 or 3. The products may be used for the production of polymers and copolymers (see Group IV(a)). |
