The reaction of naphthalene-2,3-diol 1 with PCl3 was found to furnish the hydridophosphorane 3, with PCl5 the chlorophosphorane 4 was formed. The reaction of the fluorophosphoranes, RPF4 [R=F, (i)Pr, CH2SiMe3, CH2Cl, Ph] with the bis(trimethylsilyl) derivative of 1, 2 yielded the corresponding spirocyclic phosphoranes, 5-9 by cleavage of the Si-O bond and elimination of Me3SiF. The difluorophosphoranes, R2PF3 [R=Me, Ph] reacted with 2 to form the monocyclic phosphoranes, 10 and 11, where the fluorine atom occupies an axial position at trigonal-bipyramidal (TBP) phosphorus- The structure of compound 11 was confirmed by single crystal X-ray analysis of its dichloromethane hemisolvate at -95-degrees-C. The geometry at phosphorus is trigonal-bipyramidal. whereby the naphthalenedioxy ligand spans an axial and an equatorial site. Me2PF3 reacted with tetrakis(1,2,4.5-trimethylsiloxy)benzene to form the bifunctional benzodioxa-lambda5-phosphole, 12.

The present paper describes the ring-opening-closing alternating copolymerization of cyclic phosphonites (2-phenyl-1,3,2-dioxaphospholane (1a), 2-phenyl-1,3,2-dioxaphosphorinane(1b), 2-phenyl-1,3,2-dioxaphosphepane(1c), and 2-phenyl-4H-1,3,2-benzodioxa phosphorin-4-one(1d) with muconic acid(2a), succinaldehyde(2b), glutaraldehyde(2c), adipinaldehyde(2d), o-phthalaldehyde(2e), acrylic anhydride(2f), methacrylic anhydride(2g), N-methyl diacrylamide(2h), and N-methyldimethacrylamide(2i). The reaction of a 1:1 monomer feed ratio, explained by a mechanism of propagation via zwitterion intermediates, proceeds without any added catalyst to give an alternating copolymer 3 involving ring-opening of 1 and ring-closing of 2. The structure of copolymer 3 was determined by H-1, C-13 NMR, P-31 NMR and IR spectroscopies as well as elemental analysis.

The reaction of 4-(1,3,2-benzodioxaphosphol-2-yloxy)-3-tert-butylpent-4-en-2-one with hexafluoroacetone

Catalytic (ZnCl2, Et3N) phosphorylation of tert-butylacetyl-acetone with 2-chloro-1,3,2-benzodioxaphosphole unexpectedly occurs with elimination of proton from the methyl group and leads to vinyloxyphosphole derivative, viz., 4-(1,3,2-benzodioxa-phosphol-2-yloxy)-3-tert-butylpent-4-en-2-one. Its reaction with hexafluoroacetone gives a cage phosphorane as a result of subsequent chemoselective[4+2]- and [3 + 2]-cyclo-additions with stereoselectivity above 95%.

Selectivity, acetylcholinesterase inhibition kinetics, and quantitative structure-activity relationships of a series of N-(2-oxido-1,3,2-benzodioxa-phosphol-2-yl) amino acid ethyl or diethyl esters

The inhibitory effects of a recently introduced series of the titled compounds on insect and mammalian acetylcholinesterase (AChE) activity were examined, where the median inhibition concentration (I-50) and the inhibition kinetic parameters, bimolecular inhibition rate constant (k(i)), affinity constant (K-a), and phosphorylation rate constant (k(p)), were determined for each compound. Results indicated that all examined dioxaphospholenes had less inhibitory effects on mammalian AChE than fenitrothion, a commercial pesticide with moderate mammalian toxicity. The highest selectivity was obtained with compounds containing glutamic and leucine moieties (2.70 and 2.18, respectively) while selectivity of fenitrothion was 0.93. The low inhibitory effects of the examined dioxaphospholenes on mammalian AChE were attributed to their low phosphorylation rates(k(p) < 2.2 min(-1)) compared to that of fenitrothion (k(p) = 4.84 min(-1)). QSAR equations indicated that the inhibition process is controlled mainly by both the phosphorylation rate (direct effect) and the affinity of compounds toward the enzyme (inverse effect). Although the compounds' hydrophobicity had no effects on the inhibition process, it affects the compounds' toxicity since it affects the ability of compounds to penetrate insects to reach the enzyme active site.
