The present invention provides a compound of the formula ##STR1## which inhibit squalene synthetase and cholesterol biosynthesis and are useful in the treatment of e.g., hyperlipidaemia, atherosclerosis, or fungal infections, processes for the preparation of the compounds of the invention, intermediates useful in these processes, and pharmaceutical compositions containing the compounds.
Photochemistry of the Nitrogen-Thiocarbonyl Systems, Part 31. Photoreaction of Arenecarbothioamides with 2-Vinylfuran Analogues. The Formation of Tetracyclic Indoles and 2,3-Diaryl-2-pyrrolin-5-ones.
Photoreaction of arenecarbothioamides (1) with 2-vinylfuran analogues (2, 6) in benzene aolution gave tetracyclic indole systems (3, 8) via photogenerated diarylethylene intermediates. In the case of reaction of furan- or thiophenecarbothioamide (1c, 1d) with 2-furanacrylic acid (2-i), 2, 3-diaryl-2-pyrrolin-5-ones (5c-i, 5d-i) were obtained.
A method of making polymers utilizes cyclobutane-1,3-diacid (CBDA) molecules as polymer building blocks includes and linker molecules with a non-reactive R group and at least two reactive X groups used to create chemically stable polymers of CBDA. The resulting polymers are thermally, photochemically, and chemically stable.
applicable template-directed photochemical [2+2]-cycloaddition reaction which provides access to a wide range of symmetrical and unsymmetrical cyclobutane products. The use of 1,8-dihydroxynaphthalene as a covalent template paved the way for successful and highly selective photochemical homodimerization and heterodimerization reactions in the solid state between cinnamic acid derivatives. Notably,
