Triallylborane–amines adducts are effective stoichiometric allylating agents in the aminoallylation reaction of carbonyl compounds in methanol. Moreover, copper-catalyzed diastereoselective allylation of Ellman’s imine was achieved with triallylborane–methylamine adduct.

A novel electrochemical route to generate nitriles from aldehydes under mild conditions using a catalytic amount of TEMPO (2,2,6,6-tetramethylpiperidinyl-l-oxy) as the mediator and hexamethyldisilazane as the nitrogen source in the presence of acetic acid has been developed. A variety of aromatic, heteroaromatic and aliphatic aldehydes have been converted to their corresponding nitriles in good to

Imidazoline-based small molecule inhibitors of p53-MDM2 interaction intended for the treatment of p53 wild-type tumors are the promising structures for design of anticancer drugs. Based on fragment approach we have investigated a key role of substituents in cis-imidazoline core for biological activity of nutlin family compounds. Although the necessity of the substituents in the phenyl rings of cis-imidazoline
Novel Method for the Synthesis of α-Amino-α′-hydroxyalkylphosphinic Acids and Bis(α-aminoalkyl)phosphinic Acids: Nuclephilic Addition of α-Hydroxy-H-phosphinic Acids to Diimines
here a novel and simple method for the synthesis of α-amino-α′-hydroxyalkylphosphinic acids in good yields in two simple steps without any protection–deprotection steps. We have developed an efficient method for the synthesis of α-amino-α′-hydroxyalkylphosphinic acids via the reaction of easily available α-hydroxyalkylphosphinic acids with diimines. Treatment of α-hydroxyalkylphosphinic acids with diimines
Synthesis and Complexation Properties of <i>N</i>,<i>N</i>-Bis(phosphinomethyl)amine as a New Class of 1-Aminophosphinic Acids with Transition Metals and Lanthanide Ions in Aqueous Solution
ammonia and hypophosphorus acid gave novel C2-symmetric N,N-bis(phosphinomethyl)amines as a new class of 1-aminophosphinic acid compounds. Complexation properties of N,N-bis(phosphinomethyl)amines with transition metals such as Co2+, Ni2+, Zn2+, Cu2+, and Cd2+ and lanthanide ions La3+ and Gd3+ were studied in aqueous solution by the pH-potentiometric method. Dissociation constants (pK) of the compound were
