Abstract: The process involves the free-radical copolymerisation of maleic anhydride and of vinyl alkyl ethers and the subsequent reaction of the copolymer with alkanol and is characterised in that the vinyl alkyl ether component is in excess in the reaction mixture in all phases of the polymerisation, the free-radical copolymerisation is carried out in acetone, and the acetone is removed by distillation at temperatures of up to 70 DEG C during or after the ester formation.

Abstract: (2R,6R)-1-Chloro-2,6,10-trimethyl-undecane I, (R)-(+)- beta -chloro-isobutyric acid II, (S)-(+)-1-bromo-3-chloro-2-methylpropane IV and (2R)-(+)-1-chloro-2,6-dimethyl-heptane V are novel optically active units for the synthesis of the side chain of (R,R,R)- alpha -tocopherol. In the process according to the invention, the optically active C14-chloride I is obtained in 6 simple reaction steps starting from II, via the novel intermediates IV and V, in accordance with the following equation: (II) (III) (IV) (V) (VI) &bhbrace& (VII) + (IV) (I)
