Synthesis of polyfunctionalized acylsilanes via propenoyltrimethylsilane.
Tetrahedron Letters, 1987Abstract Propenoyltrimethylsilane (1) reacts with silylated nucleophiles to yield the β-functionalised silyl enol ethers of acylsilanes. Further “in situ” reaction of these compounds affords an easy entry into the class of polyfunctionalised acylsilanes.

Phosphorus, Sulfur, and Silicon and the Related Elements, 1993
Abstract The thieno[3,4-d]pyridazine derivatives 1a, b reacted with acrylonitrile to afford the mercaptophthalazine derivatives 6a, b. The latter products reacted with acrylonitrile again to afford 11a, b. With maleic anhydride and N-phenylmaleimide they afforded 13a-d respectively.

Pentagonal Dodecahedranes: Polyfunctionalization and MS Fragmentation
The Journal of Organic Chemistry, 2001With the use of four- to eight-fold functionalized dodecahedranes (1-3), opportunities to arrive at highly strained dodecahedranes with two to four pairs of vicinal, eclipsed bromine substituents through front-side substitution and addition reactions have been explored.

Synthesis and cytostatic properties of polyfunctionalized furanoallocolchicinoids
European Journal of Medicinal Chemistry, 2017A series of furan-based allocolchicinoids was prepared from commercially available colchicine via a nine-step reaction sequence. Cytostatic activity, cell cycle arrest, apoptosis, tubulin and F-actin expression were studied in vitro in 2D and 3D cultures of normal and tumor epithelial keratinocytes, endothelial and mesenchymal cells. Among the prepared

Synthesis of polyfunctionalized methylphosphine oxides
Russian Chemical Bulletin, 2012N,N-Dialkylamino(diphenylphosphoryl)chloromethanes, a new type of organophosphorus compounds, were synthesized. On dissolving in polar and low polar solvents, N,N-dialkylamino(diphenylphosphoryl)chloromethanes dissociate spontaneously with the P—C bond cleavage to form the diphenylphosphinite anion Ph2PO−.

Polyfunctionality of Horse Liver Alcohol Dehydrogenase
1980Horse liver alcohol dehydrogenase (LADH; EC 1.1.1.1) is today one of the most thoroughly investigated enzymes. Since its crystallization in 1948 (1) many authors have studied its properties in great details: the Swedish school, first with Theorell and then with Branden and their co-workers, has extensively reviewed our knowledges on this and related ...

Polyfunctionally Pyrazole Azo Dyes
Pigment & Resin Technology, 1994In recent years heterocyclic azo dyes have been the subject of an intense research by dye manufacturers. Even so, little has been devoted to technical properties, so we have recently directed our research activities towards studying the ability of thiazole azo and hydrazono disperse dyes for dyeing of polyester and cellulose acetate.

Synthesis of polyfunctionally substituted pyridazines
Liebigs Annalen der Chemie, 1990AbstractThe pyridazines 3, 4, 5, and 7 were obtained by reaction of the hydrazone derivatives 2 with several reagents. By treatment of 5 with acetic acid/hydrochloric acid, the pyrazolo[4,3‐c]‐pyridazine 6 was formed. The pyrido‐pyridazine derivatives 8 and 9 were obtained by reaction of 2 and 3 with malononitrile and ethyl cyanoacetate, respectively ...
