NMR evidence also suggests the degenerate rearrangement via the anhydride derivative (159). A similar process was described for the chemistry of succinic and glutaric anhydrides in superacid. The methyl ester of... 

In the synthesis of (S)-zearalenone and of a chiral spiroac-etal, (2S,6/ )-2-methyl-l,7-dioxaspiro[5.6]dodecane, the starting product was a functionalized 3-keto sulfoxide resulting from the reaction of glutaric anhydride with lithiated (+)-(7 )-methyl p-tolyl sulfoxide (eq 6).

Paniculide-A is structurally the least complicated of the paniculides, a family of highly oxygenated sesquiterpenes from Andrographis paniculata. Jacobi s synthesis of paniculide-A began with a four-step conversion of 3-methyl glutaric anhydride 175 to the oxazole acetylenic ketone 176 (Fig. 3.54). Cycloaddition of... 

DMAP is an efficient desynmetrisation catalyst. [Wilhs J Chem Soc, Perkin 1 1765 7999.] Thus it allows the use of an achiral or meso molecule, e.g. 3-substituted gjutaric anhydride to react with chiral alcohols e.g. 7 -l-(l -naphthyl)ethanol to produce (l 7 ,37 )-l(r-naphthyl)ethyl methyl 3-substituted-pentanoate di-esters (after treatment with diazomethane), which are now chiral at C-3. The achiral carbon atom at C-3 in the glutaric anhydride becomes chiral in the pentanoate (mono-ester of glutarate).

The N-terminus of peptide sequences obtained from solid phase synthesis was transformed into a carboxylic acid group by the action of glutaric anhydride. NMP initiator tethered to the N-terminus of the peptide was then introduced via reaction of the benzyUc amine of a fluorine-labeled alkoxyamine with the previously modifled peptide. The peptide-supported initiator was then used to create block copolymers, under conditions that promote sequential NMP of terf-butyl acrylate and methyl acrylate [84],... 

An example of this isomerization involving the thermal rearrangement of a polymeric anhydride of tranj-1,2-dimethylcyclopropane-l, 2-dicar-boxylic acid to a corresponding anhydride of y-methyl-a-methylene glutaric acid was described as early as 1934 von Auwers, K. Ungemach, O. Liebigs Ann. Chem. 1934, 511, 152. McGreer, D. E. Chiu, N. W. K. McDaniel, R. S. Proc. Chem. Soc. London 1964, 415. 

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. 

A. N. Dey (174) has described an independent synthesis of the alkaloids. Michael condensation of ethyl 7-ethoxy- or 7-phenoxy-crotonate (LI, R = OEt, R = Et or Ph) with ethyl malonate or cyan-acetate, followed by ethylation and hydrolysis, furnished a mixture of the two racemic forms of the glutaric acid, LII, which were separated by virtue of their different ease of anhydride formation. On treatment with hydrobromic acid, they gave rise to dl-homopilopic acid and dl-homo-isopilopic acid (LIII, R = OH), respectively. Corresponding methyl ketones (LIII, R = Me) were obtained by a similar synthesis from...
