    取代的反式-4-氨基-3,4-二氢-2,2-二甲基-2H-1-苯并吡喃-3-醇的合成及降压活性。
    摘要:
    制备了一系列新型取代的反式-4-氨基-3,4-二氢-2,2-二甲基-2H-1-苯并吡喃-3-醇,并在有意识的乙酸脱氧皮质酮(DOCA)/盐水处理中测试了其降压活性。高血压大鼠。最佳的降血压活性需要一个强的吸电子基团与6位上的吡咯烷基或哌啶子基团一起进行6位取代。7-硝基-4-吡咯烷类似物和6-硝基-3-氯丙胺的例外,它们保留了明显的降压活性。所有这些化合物都是直接的血管扩张药,并且具有与肼屈嗪和钙拮抗剂硝苯地平相当的降压活性。这些化合物的合成路线包括将炔丙基醚环化为2H-1-苯并吡喃,然后通过溴代醇转化为3,4-环氧化物,用适当的胺开环。间取代的炔丙基醚在热环化反应中同时产生5-和7-取代的苯并吡喃,前者占优势。描述了一种新的制备2,2-二甲基-7-硝基苯并吡喃的途径。

  • Synthesis of Pterocarpans by Means of a “Disfavored” 5-endo-trig Radical Cyclization Reaction
    作者:Kalpathy Chidambareswaran Santhosh、Ariamala Gopalsamy、Kalputtu Kuppuswamy Balasubramanian
    DOI:10.1002/1099-0690(200109)2001:18<3461::aid-ejoc3461>3.0.co;2-9
    日期:2001.9
    A successful synthesis of pterocarpans 1, based on a "disfavored" 5-endo-trig radical cyclization reaction, has been accomplished. The radical precursor 4-(2'-bromoaryloxy)-2H-chromene 8 was synthesized in six steps, starting from aryl propynyl ether 2. On treatment with tributyltin hydride in refluxing benzene, aryl enol ether 8 underwent radical cyclization to furnish the pterocarpan 1. A deuterium

  • 6-Substituted Benzopyrans as Potassium Channel Activators:  Synthesis, Vasodilator Properties, and Multivariate Analysis

    During the last 10 years compounds have been discovered which can activate or block K-ATP channels. In particular, K channel activators (KCA)have been found to be smooth muscle relaxants with their main utility in hypertension and bronchodilation. In this paper we describe the synthesis of new KCA of the benzopyran type with a fixed 4-substituent and a systematic variation in the 6-position. The relaxant potency in rat aorta and trachea was used for biological characterization of the benzopyrans. In both biological test systems, they exhibit potency ranges of more than 3 log units. Structure-activity relationships are investigated by principal component analysis (PCA) and partial least-squares (PLS) analysis. Most striking outliers in an initial PLS analysis of the entire database were the unsubstituted 6-H compound 13 as well as 34 and 35. For the remaining set of 31 compounds, a S-component PLS model explains the variance in biological activity to 81% in the aortic and to 82% in the tracheal test system. 6-Substituents influence affinity by a direct (presumably dipolar) interaction with the receptor site. According to the 2D-plot of the partial PLS weights, a strong electronegativity as well as high values for the integy moment and for the heat of formation in water dominate the first component; low values for substituent size (as defined by globularity or surface) are in addition favorable for high potency. High lipophilicity and low minimum energies of interaction dominate the second component. Chemical descriptors for the biological potency of the test set in rat aorta and rat trachea are very similar according to the almost identical projection of the Y-variables onto the X-component space.
