Scandium-Catalyzed Intramolecular Friedel–Crafts Reactions of 2-[(2-Alkyl-1H-indol-3-yl)methylene]malonates
摘要:
We have synthesized a variety of 2-[(2-alkyl-1H-indol-3-yl)methylene]malonates and studied their scandium-catalyzed intramolecular Friedel-Crafts reactions leading to the corresponding polycyclic compounds such as indeno[1,2-b]indoles and benzo[1,2-b]carbazoles.
Knoevenagel-type indoles is described. The method is based on the in situ reaction of indole iminiumsalts (four of them are fully characterized) with acyclic symmetrical and unsymmetrical active methylene reagents in the presence of triethylamine. In general, the overall yields are moderate to good. Some of relevant reaction parameters and steric effects affecting stereoselectivity are discussed.

3-disubstituted indoles from alkyne iminoethers 1 that employs a domino process involving Ag-catalyzed condensation followed by a tandem Ag-induced cycloisomerization and 1,3-alkenyl shift to Ag-activated carbon. This methodology can be useful in regioselectively constructing 3-alkylated indoles, which are part of the structures of biologically active compounds and important alkaloids.
This invention relates to chemical uncouplers with a broader safety window making the use of them in treating obesity and, consequently, in the treatment of obesity related diseases and conditions such as atherosclerosis, hypertension, diabetes, especially type 2 diabetes (NIDDM (non-insulin dependent diabetes mellitus)), impaired glucose tolerance, dyslipidemia, coronary heart disease, gallbladder disease, osteoarthritis and various types of cancer such as endometrial, breast, prostate and colon cancers and the risk for premature death as well as other conditions, such as diseases and disorders, which conditions are improved by an increase in mitochondrial respiration, more attractive.
