    Abstract: A process for the preparation of a compound or polymer having at least one functional group selected from hydroxyl, thiol, amino and carboxylic acid groups is characterized in that a compound or polymer (A) containing a group of formula (I), where Q represents O or S and X represents -O-, -S-, -NH- or a direct bond, the group being linked to the remainder of the compound or polymer through a carbon atom, is reacted with a compound (B) containing at least two functional groups selected from hydroxyl, thiol, amino and carboxylic acid groups, one of which functional groups (II) reacts with the group of formula (I) and one of which functional grops (III) is substantially unreactive with the group of formula (I) under the conditions of reaction, so that the compound (B) becomes bonded to (A) through the reaction of groups (I) and (II) forming a compound or polymer containing unreacted functional groups (III). The invention also includes dendritic polymers obtainable by the process and intermediates obtainable in the process.

    Abstract: A process whereby both enantiomers of optically active alpha -hydroxy- gamma -butyrolactone, which are useful as medicinal intermediates, can be conveniently produced from inexpensive and easily available materials. Optically active alpha -hydroxy- gamma -butyrolactone is produced by reacting an optically active 4-amino-2-hydroxybutanoic acid derivative with nitrous acid and cyclizing under acidic conditions. Further, (S)- alpha -hydroxy- gamma -butyrolactone is reacted with sulfonyl chloride in the presence of a base to give (S)- alpha -sulfonyloxy- gamma -butyrolactone. It is further reacted with a carboxylic acid salt to give (R)- alpha -acyloxy- gamma -butyrolactone which is then deacylated by treating with an acid or a base in an alcoholic solvent to give (R)- alpha -hydroxy- gamma -butyrolactone.
