The present invention relates to [1,2,4]triazolo[1,5-c]pyrimidine derivatives of formula (I) which inhibit the activity of Heat Shock Protein Hsp90. The compounds of the invention are therefore useful in treating proliferative diseases such as cancer and neurodegenerative diseases. The present invention also provides processes for preparing these compounds, methods of treating diseases and the pharmaceutical compositions comprising these compounds.

utilize an enantiopure biaryl common intermediate, which is formed via an enantioselective catalytic biaryl coupling. The established axial chirality is transferred to the perylenequinone helical stereochemistry with good fidelity. Additionally, efforts focused on the installation of the stereogenic C7,C7′-2-hydroxypropyl groups. Three routes were evaluated to establish the C7,C7′-stereochemistry, in which
概述了 (+)-calphostin D 的第一次全合成和 (+)-phleichrome 的全合成。收敛合成利用对映纯的联芳基共同中间体,其通过对映选择性催化联芳基偶联形成。建立的轴向手性以良好的保真度转移到苝醌螺旋立体化学。此外,努力集中在立体 C7,C7'-2-羟丙基基团的安装上。评估了三种路线以建立 C7,C7'-立体化学,其中成功的路线涉及具有复杂轴向手性双铜酸盐的双环氧化物烷基化。

A number of 6-alkyl-12-formyl-5,6-dihydroindolol[2,1-a]isoquinolines were synthesized by the Bischler-Napieralski reaction from the respective 1-alkyl-2-(3-methoxyphenyl)ethylamines and bromo-substituted (methoxyphenyl)acetic acid chlorides followed by a second ring closure reaction involving a base-generated benzyne intermediate. The methoxy functions in positions 3 and 9 or 10 were cleaved with BBr3
