phosphinates and some H-phosphonate diesters is promoted by the base DBU. Only more reactive alkyl halides react in preparatively useful yields. However, the method provides easy access to important H-phosphinate buildingblocks, without the need for a protecting group strategy or metal catalysts. The reaction is conveniently conducted at, or below, room temperature. The preparation of methyl-H-phosphinate

Convenient methods for the synthesis of functionalized organophosphorus compounds containing carbonyl groups as well as di- or trialkoxymethyl fragments attached to phosphorus, and their derivatives, starting from the available derivatives of trivalent phosphorus acids, are proposed, and some properties of the new functionalized organophosphorus compounds are presented. So, the alkylation and acylation

Convenient procedures for the synthesis of newalkoxy(trimethylsiloxy)phosphines and their derivatives starting from the available alkyl hypophosphites and N-trimethylsilyl succinimide are proposed. Some properties of these new phosphines such as nucleophilic substitution of the trimethylsiloxy group at trivalentphosphorus, the Arbuzov reaction, and addition of PH and POSi fragments to multiple carbon–carbon

A novel and practical approach to monosubstituted phosphinic acid (alkylphosphonous acid) derivatives from hypophosphite salts or esters is described. Phosphorus-centered radical formation is initiated with Et(3)B/O(2), and the reaction is conveniently conducted at room temperature in an open flask. In contrast to previously reported conditions for the radical reaction of hypophosphorous acid and sodium

The rational design, synthesis, and biological activity of phosphonyl- and phosphinyl-linked bisubstrate analoginhibitors of the enzyme Ras farnesylproteintransferase (FPT) are described. The design strategy for these bisubstrate inhibitors involved connection of the critical binding components of the two substrates of FPT (ras protein and farnesylpyrophosphate, FPP) through a phosphonyl- or phosphinyl-bearing
