Dimethyl azelate

The preparation of several medium- and large-sized 2-carbo-methoxycycloalkanones has been accomplished by treatment of the cycloalkanone with sodium triphenylmethyl, followed by carbonation with dry ice, and esterification with diazomethane. 1 The yields are good but the procedure is laborious. The synthesis of 2-carbomethoxycycIooctanone via the Dieckmann cyclization of dimethyl azelate with sodium hydride yields 48% of this product when the procedure is carried out over a 9-day period.3... [Pg.22]

There is only one report in the literature concerning Astragalus essential oil. Miyazawa in 1987 [214] has studied the volatile flavour of "Astragali radix" (the root of A.membramceus, that has a good note and a dry green mild fruity odor), obtained by steam distillation under atmosferic pressure of the macerated roots twenty-two components have been identified by GC, GC-MS, IR and NMR analyses. They include 9 dimethylesters of dicarboxilic acids, 14 methylesters of fatty acids, 2 aldehydes, 1 ketone, 4 alcohols and 1 acid. Methyl palmitate is the main component (22.0 %), followed by dimethyl azelate (16.2 %), a compound with a fhiity-winey odor such as the dimethyl esters of dicarboxilic acids. [Pg.479]
