New compounds, 2-(6'-methoxynaphth-2'-yl)propylene oxide, 2-(6'-methoxynaphth-2'-yl)propionaldoxime, 2-hydroxy-2-(6'-methoxynaphth-2'-yl)-propionitrile, 2-(6'methoxynaphth-2'-yl)acrylonitrile, 2-(6'-methoxynaphth-2'-yl)acrylic acid, the corresponding 5'-halo compounds and 2-(5'-halo-6'-methoxynaphth-2'-yl)propionaldehyde are useful intermediates in producing 2-(6'-methoxynaphth-2'-yl)propionic acid and the corresponding 5'-halo acids from 6-methoxy-2-acetylnaphthalene and the corresponding 5-halo compounds. The 2-propionic acids are anti-inflammatory, analgesic, anti-pyretic and anti-pruritic agents. The 2-propionaldehydes, obtained from the 2-acetyl compounds by way of the 2-propylene oxide, can be converted directly to the 2-propionic acids by way of the 2-propionaldoximes and the 2-propionitriles or more directly by Jones oxidation. Alternatively the 2-acrylonitriles, obtained from the 2-acetyl compounds by way of the 2-hydroxy-2-propionitrile, can be converted to the 2-propionic acid by way of the 2-acrylic acid or 2-propionitrile.
新化合物,2-(6'-甲氧基萘-2'-基)丙烯氧化物,2-(6'-甲氧基萘-2'-基)丙醛肟,2-羟基-2-(6'-甲氧基萘-2'-基)-丙腈,2-(6'甲氧基萘-2'-基)丙烯腈,2-(6'-甲氧基萘-2'-基)丙烯酸,对应的5'-卤代化合物和2-(5'-卤基-6'-甲氧基萘-2'-基)丙醛是从6-甲氧基-2-乙酰基萘和对应的5'-卤代化合物中生产2-(6'-甲氧基萘-2'-基)丙酸和对应的5'-卤代酸的有用中间体。2-丙酸具有抗炎、镇痛、退热和抗瘙痒作用。从2-乙酰基化合物通过2-丙烯氧化物获得的2-丙醛可以通过2-丙醛肟和2-丙腈或更直接地通过琼斯氧化直接转化为2-丙酸。另外,从2-乙酰基化合物通过2-羟基-2-丙腈获得的2-丙腈可以通过2-丙烯酸或2-丙腈转化为2-丙酸。
