Carbamoyloximes as novel non-competitive mGlu5 receptor antagonists
摘要:
Hit-to-lead optimization of a HTS hit led to new carbamoyloxime derivatives. After identification of an advanced hit (8d) the CYP enzyme inhibitory activity of this class of compounds was successfully eliminated. Systematic exploration of different parts of the advanced hit led us to some promising lead compounds with mGluR5 affinities comparable to that of MPEP. (C) 2010 Elsevier Ltd. All rights reserved.

Trialkylsilyl triflimides generated in situ are unique catalysts for the electrophilic benzylation or allylation of trialkylsilylenol ethers or allyl trialkylsilanes with non-genotoxic alkylating reagents such as benzyl and allyl acetates. In most cases the reactions are fast at room temperature and yields are high. The reaction works particularly well with electron-rich benzyl donors including derivatives
The baker'syeastreduction of arylidene cycloalkanones 5, 6 and 7 occurs initially through the catalysis of different enzymes to give the saturation of the double bond leading to the saturated ketones 9, 15 and 22 and the carbonyl reduction to the (S) allylic alcohols 8a, 14 and 23, possessing 0.99. 0.85 and 0.66 ee, respectively The latter act as inhibitors for the carbonyl reducing enzyme thus preventing
Herein, we report the development of an efficient green procedure for synthesizing carbonyl furanderivatives by dehydrogenative coupling of furfuryl alcohol with carbonyl compounds. The reaction is performed under mild reaction conditions in the presence of iPrPNP-Mn as the catalyst and a weak base (Cs2CO3). A range of ketones and aldehydes were efficiently diversified with furfuryl alcohol to afford
在此,我们报告了通过糠醇与羰基化合物的脱氢偶联来合成羰基呋喃衍生物的高效绿色工艺的开发。该反应在温和的反应条件下在iPr PNP-Mn 作为催化剂和弱碱 (Cs 2 CO 3 ) 的存在下进行。一系列酮和醛与糠醇有效地分离,以良好的分离收率提供呋喃基取代的饱和酮和 α,β-不饱和酮和醛。
