Cashew nut shell liquid (CNSL) is a natural aromatic organic oil consisting of phenolic compounds with interesting structures. Extraction of CNSL was performed in a Soxhlet apparatus. The major (90 %) component of CNSL is anacardic acid, which is easily decarboxylated to cardanol (10 %) by use of conventional methods. In this paper we describe a three-step synthesis of Mannich polyols for rigid foams
腰果壳油(CNSL)是一种天然芳香有机油,由具有有趣结构的酚类化合物组成。CNSL的提取在索氏提取器中进行。CNSL的主要(90%)成分是茴香酸,通过常规方法很容易将其脱羧为腰果酚(10%)。在本文中,我们描述了用于刚性泡沫的曼尼希多元醇的三步合成。第一步是通过低聚甲醛和二乙醇胺的缩合反应合成 N- (2-羟乙基)-1,3-恶唑烷(曼尼希前体)。第二步涉及通过与 N- (2-羟乙基)-1,3-恶唑烷反应来合成腰果酚的曼尼希碱酚环 。第三步是烷氧基化。FTIR和1表征了合成的多元醇1 H NMR光谱和薄层色谱。

A series of 8-substituted quinolines were synthesized and tested against seizures induced by maximal electro shock (MES), pentylenetetrazole (scMet) and antihypertensive activities. Neurologic deficit was evaluated by the rotarod test. Among the newly synthesized derivatives, several compounds with a 2-hydroxypropyloxyquinoline moiety displayed excellent anticonvulsant and antihypertensive activities. Compound 20 (8-(3′-(4″-phenylpiperazino)-2′-hydroxypropyloxy)quinoline) was potent in both series as an anticonvulsive agent. 13 (8-(3′-piperazino)-2′-hydroxypropyloxyquinoline) and 14 (8-(3′-imidazolo)-2′-hydroxypropyloxyquinoline) showed very good anticonvulsant activities in the propanol series of compound, whereas in the ethane series, 1 (8-(2′-piperazino-ethanoxy)quinoline) and 2 (8-(2′-imidazolo-ethanoxy)quinoline) were the most active as anticonvulsive agents. Compounds 20 (8-(3′-(4″-phenylpiperazino)-2′-hydroxypropyloxy)quinoline), 13 (8-(3′-piperazino)-2′-hydroxypropyloxyquinoline) and 19 (8-(3′-(4″-ethylpiperazino)-2′-hydroxypropyloxy)quinoline) have shown excellent antihypertensive activity. They have significantly antagonized the pressor response elicited by adrenaline. These pharmacological results suggest that their anticonvulsant and antihypertensive effects may be correlated to the presence of β-blocking properties, and that those properties depend on the presence of aryloxypropanolamine.
