Abstract:
Diorganotinbis(O-alkyl alkylphosphonate)s, R2Sn(O2P(OR1)R1)2 [R1 = Me, R = Me (1), Et (2), n-Bu (3); R1 = Et, R = Me (4), Et (5), n-Bu (6)] have been synthesized from the reaction between dimethyl/diethyl/di-n-butyltin dichloride and dialkyl alkylphosphonates, (R1O)2P(O)R1, in a solvent-free medium (120 °C, 18 h). X-ray crystal structure of 1 reveals two independent molecules in the unit cell that form one-dimensional polymeric motifs by virtue of bridging bidentate phosphonate groups. The structural attribute of each polymeric chain represents an orderly infinite array of -[Sn-O-P-O-]2 8-memb

Abstract:
Coumarins are an important class of natural heterocyclic compounds that have attracted considerable synthetic and pharmacological interest due to their various biological activities. This review emphasizes on the synthetic methods for the preparation of dialkyl 2-oxo-2H-1-benzo- pyran-3-phosphonates and alkyl 1,2-benzoxaphosphorin-3-carboxylates. Their chemical properties as acceptors in conjugate addition reactions, [2+2] and [3+2] cycloaddition reactions are discussed.

Abstract:
The influence that intramolecular catalysis of hydrolysis of O-alkyl S-[2-( dialkylamino )ethyl] alkylphosphonothioates by amino groups may have on the product distribution of the reaction is investigated by study of a series of model compounds. The hydrolysis of diethyl [ω-( ethylamino )alkyl] phosphonates and diethyl [ω-( diethylamino )alkyl] phosphonates has been investigated at 75°C over the pH range 8.21-11.45. Contributions to hydrolysis of the ethoxy groups by intramolecular catalysis by the amino groups have been identified for [2-(amino)ethyl]- and [3-(amino) propyl ]- phosphonates. S

Abstract:
For its high therapeutic effect, (S)-9-[3-hydroxy-2-(phosphonomethoxy)propyl]adenine (HPMPA) is an important member of a class of acyclic nucleoside phosphonates (ANPs). Although its constitutional isomer, 9-[2-hydroxy-3-(phosphonomethoxy)propyl]adenine (iso-HPMPA), exhibits no antiviral activity, our general interest in C-8 substituted adenine ANPs led us to prepare certain iso-HPMPA derivatives modified at the C-8 position of adenine. Novel alkylating agent, diisopropyl {[2-(tetrahydro-2-pyranyl)oxy-3-tosyloxypropoxy]methyl}phosphonate (9), was prepared by procedure starting from allyl alcoh

Abstract:
A simple and efficient microwave (MW)-assisted method was elaborated for the catalyst-free synthesis of isoindolin-1-one-3-phosphonates by the three-component condensation of 2-formylbenzoic acid, aliphatic primary amines and various dialkyl phosphites. The batch and the continuous flow reactions were optimized in respect of the temperature, the reaction time and the molar ratio of the starting materials. To evaluate the potential of MW irradiation, comparative thermal experiments were also carried out. In order to obtain “real time” information about the condensation, the special Kabachnik–Fi
