Methyl 1-naphthyl

Naphthylacetic acid derivatives, showiag antiinflammatory, analgesic, and antipyretic activities ate prepared by Ftiedel-Crafts acylation of methyl 1-naphthyl acetate at the 4 position with (CH2)2CHCOCl followed by Clemmensen reduction (97).

Methyl 1-naphthyl ether [2216-69-5] M 158.2, b 90-91°/2mm, d 1.095, n26 1.6210. Steam distd from alkali. The distillate was extracted with ethyl ether. After drying the extract and evaporating the ethyl ether, the methyl naphthyl ether was distd under reduced pressure. 

A remarkably high diastereoselective excess was obtained in the addition of the anion of (S)-(-)-methyl 1-naphthyl sulfoxide to n-alkyl phenyl ketones. The sulfoxide was prepared in optically pure form by oxidation of the complex of methyl 1-naphthyl sulfide and 13-cyclodextrin with peracetic acid followed by crystallization. Desulfurization of the adducts provided enantiomerically pure tertiary alcohols (393]. 

Under the conditions favorable for the synthesis of pyrroles from alkyl aryl ketoximes (100°C, 3 hr, 30% KOH of ketoximes mass, DMSO, acetylene under 12-16 atm pressure), the reaction with methyl naphthyl ketoximes is accompanied by considerable resinification to give low yields of pyrroles 14-17. The best results were achieved at 90°C. From methyl 1-naphthyl ketoxime at this temperature (2 hr, KOH), 2-(l-naphthyl)pyrrole (14) and 2-(l-naphthyl)-1-vinylpyrrole (15) are formed in 15 and 48% yield, respectively. 

In general, however, methyl 1-naphthyl ketoxime starts to condense with acetylene under pressure at about 60°C. At 80°C (3 hr, KOH) 2-(l-naphthyl)- 1-vinylpyrrole (15) becomes the predominant reaction product, however its yield decreases due to resinification on further elevating the temperature and increasing the reaction time. 2-(l-Naphthyl)pyrrole (14), free from the corresponding N-vinylpyrrole (15), was isolated in 22% yield when use was made of a catalytic pair LiOH/DMSO (90°C, 3 hr). The temperature effect (3 hr, 30% KOH, initial acetylenic pressure of 12 atm) on the yield of naphthylpyrroles was examined in condensation of methyl 2-naphthyl ketoxime with acetylene as an example (82KGS1351) ...
