One-pot synthesis of α-aminophosphonates via a cascade sequence of allylamine isomerization/hydrophosphonylation

A Rh/Ni-catalyzed cascade sequence of allylamine isomerization and hydrophosphonylation to synthesize α-aminophosphonates has been disclosed. The reaction, which not only allows the generation of widespread valuable α-aminophosphonates under simple system

Conversion of nitriles to 1-aminophosphonic acids and preparation of phosphahomocysteines of high enantiomeric excess

A variety of nitriles was reduced to diisobutylaluminum salts of aldimines, to which diisopropyl phosphite was added. The corresponding 1-aminophosphonates were either deprotected to give racemic 1-aminophosphonic acids or reacted with Boc2O to yield N-Boc-protected 1-aminophosphonates. The enantiomers of 2-benzylthio-1-(t-butoxycarbonylamino)propylphosphonate were obtained from the racemate by chiral HPLC and converted to phosphonic acid analogs of (R)- and (S)-homocysteine, (R)- and (S)-2-aminobutyric acid and (S)-methionine, all of ee >97% as determined by chiral HPLC.

Tritylamine (triphenylmethylamine) in organic synthesis; III. The synthesis of 1-aminoalkylphosphonic acids in the reaction of N-(triphenylmethyl) alkanimines with phosphorus trichloride in acetic acid or with phosphonic (phosphorous) acid in acetic anhydride

The reaction of phosphorus trichloride in acetic acid or phosphonic (phosphorous) acid in acetic anhydride, with N-(triphenylmethyl)alkanimines gives 1-acetylaminoalkylphosphonic acids 1a-j, which after hydrolysis give 1-aminoalkylphosphonic acids 2a-j in good yields. ARKAT USA, Inc.

3-phenyl-pyrones

Novel 3-phenyl-pyrones of the formula in which A, D, X and Y are each as defined in the description, a process for preparing these substances and their use as pesticides, fungicides and herbicides.

Utilization of 3-phenyl-pyrones for pest control

3-Phenyl-pyrones of the formula in which x represents pyrid-2-yl and Y represents fluorine, or x represents 4-fluoro-phenyl and Y represents chlorine, are highly suitable for use as pesticides, fungicides and herbicides.

Arylphenyl-substituted cyclic keto enols

The present invention relates to novel arylphenyl-substituted cyclic ketoenols, their preparation and the use of such ketoenols as pesticides and/or herbicides. The novel arylphenyl-substituted cyclic ketoenols are of the formula (I) in which CKE refers to the cyclic ketoenol and W, X, Y and Z are as defined in the specification.

The formation of α-amino- and α-hydroxy-alkanephosphonic acids in the reactions of phosphite esters with aldehydes and alkyl carbamates

The preparation of α-aminoalkanephosphonic acids from triphenyl phosphite, an aldehyde, and ethyl or benzyl carbamate in glacial acetic acid, followed by hydrolysis, is accompanied by the formation of the corresponding α-hydroxyphosphonic acid. Reaction in toluene, using boron trifluoride-etherate as catalyst, affords an alternative preparative procedure but does not prevent the formation of α-hydroxyphosphonic acid. 31P nmr reveals the presence of numerous intermediates. The reactions are discussed.
