Synthesis of Polyfunctionalized Hexahydropyrimidines

Russian Journal of Organic Chemistry, 2019
The reactions of alkyl 5-acetylhexahydropyrimidine-5-carboxylates with ammonia, hydrazine hydrate, and lithium aluminum hydride were used to synthesize hexahydropyrimidine derivatives containing pharmacophoric 1,3-propylenediamine and 1,3-propanolamine fragments.

Implications of the polyfunctionality of hemopoietic regulators

Stem Cells, 1994
Studies on the expanding group of hemopoietic regulators have identified several types of situations indicating the polyfunctionality of these regulators. In actions on hemopoietic populations, this polyfunctionality is seen in cross-lineage actions, in proliferative actions on cells at multiple stages within a lineage and, above all, in actions that ...

Synthesis of polyfunctionalized acylsilanes via propenoyltrimethylsilane.

Tetrahedron Letters, 1987
Abstract 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.

STUDIES WITH POLYFUNCTIONALLY SUBSTITUTED HETEROAROMATICS: A NEW ROUTE TO POLYFUNCTIONALLY SUBSTITUTED ANNELATED MERCAPTOPHTHALAZINES

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.

Synthesis and cytostatic properties of polyfunctionalized furanoallocolchicinoids

European Journal of Medicinal Chemistry, 2017
A 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
