Glutaric acid anhydrides

Glutarimides may be regarded as oxidized piperidines, and many drugs containing this moiety are sedatives and anticonvulsants. A spiro derivative, alonimid (105) is such a sedative-hypnotic agent. It can be prepared by K t-butoxide catalyzed biscyano-ethylation of phenylacetonitrile, leading to 101. Alkaline hydrolysis produces tricarboxylic acid 102 which is smoothly Converted to the glutaric acid anhydride (103) with acetic anhydride. Friedel-Crafts... [Pg.295]

The favored orientation of phenyl rings attached to cyclohexane (144) in glutaric acid anhydride 28 (145) and 1,3-dioxane 29 (146) rings has also been successfully worked out without invoking the 7T-MO system 30a is favored over 30b. [Pg.139]

During alcoholysis of racemic substituted glutaric acid anhydride one is faced with regio- and enantioselectivity. These two processes may not cooperate in a matching sense. Despite this fact, the monoalkyl glutarates 19-21 have been obtained with moderate to good enantiomeric excess by lipase-catalyzed alcoholysis of the corresponding anhydrides in the presence of Candida antarctica B lipase with 2-methyl-propanol. [Pg.558]

Aliphatic dicarboxylic acid dichlorides were applied to the surface-saponified blend of 50 wt% poly(ethylene-co-propene) and 50 wt% poly(ethylene-co-vinyl acetate) (PP/EVA). After coupling without cyclization, the second carboxylic acid group is available for the covalent binding of the protein via the W-terminal amino group [ 140]. The use of anhydrides, e.g. glutaric acid anhydride, is another possibility to introduce free carboxyl groups into the polymer surface. [Pg.38]

The polyABHG chains grafted onto the Tecoflex surface assume the function of a spacer and present free carboxylic groups. In order to achieve similar structures at the model surface, PHBA was reacted with glutaric acid anhydride as a spacer molecule. The covalent bond between the glutaric acid anhydride and the PHBA surface was proven using SIMS [146]. The free carboxylic groups on the... [Pg.42]
