phosphonate. Three phosphonodipeptides containing ethyl 1-amino-2-phenylethylphosphonamidate were also prepared by converting phosphono monoacid into phosphonochloridate and reacting it with amino acid ester. Benzyl ethoxyphosphonyl-glycyl-glycine ethyl ester also was synthesized from ethyl glycylglycinate and ethyl benzylphosphonochloridate derived from direct chlorination of diethyl benzylphosphonate

Benzylphosphonates of 5 ’ -norcarbocyclic analogue of 2 ’ ,3 ’ -dideoxy-2 ’ ,3 ’ -didehydrouridine and its N 3 -benzyl derivatives with different substituents at the phosphorus atom were designed and synthesized in attempt to improve solubility of potential non-nucleoside reverse transcriptase inhibitor. Solubility of the most hydrophilic representative was 400 mg in 100 ml of 1% DMSO solution in water
Transition metal-free access to 3,4-dihydro-1,2-oxaphosphinine-2-oxides from phosphonochloridates and chalcones through tandem Michael addition and nucleophilic substitution
A novel and transition metal-free synthesis of 3,4-dihydro-1,2-oxaphosphinine 2-oxides was developed. LiHMDS-mediated tandem Michael addition and nucleophilicsubstitution of readily available phosphonochloridates and chalcones afforded a variety of valuable 3,4-dihydro-1,2-oxaphosphinine 2-oxides bearing diverse functionalities in excellent yields and satisfactory to good diastereoselectivity (up

A novel and transition metal-free synthesis of benzo-δ-phosphonolactams from readily available ethyl arylmethylphosphonochloridates and dibenzo[b,f][1,4]oxazepines was developed. The reaction includes tandem phosphonylation, deprotonation, intramolecular nucleophilic addition, and aromatization, affording various polycyclic benzo-δ-phosphonolactams in moderate to good yields and diasteroselectivity
