Synthesis of penta- and hexa-m-phenylenecyclophosphites and thiophosphates

New representatives of an original crown ether class-penta- and hexaresorcinolamidophosphites (7a,b and 13a,b)-were synthesized using the molecular assemblage technique. Their thio derivatives (8a,b and 14a,b) were obtained, as well as the rhodium (I) complex of hexaphosphite 13b (16). Macrocycle 15 containing both P3+ and P5+ was synthesized. 1H and 31P NMR spectroscopy data suggested the higher conformational flexibility of phosphite macrocycles.

Novel Di-isopropylamino Derivatives of Trivalent Phosphorus

Reduction of (iPr2N)2PCl with LiAlH4 in diethyl ether gives (iPr2N)2PH; reaction of iPr2NPCl2 with Mg in boiling tetrahydrofuran gives either the cyclotetraphosphine (iPr2N)4P4 or the 1,2-dichlorobiphosphine iPr2NP(Cl)-P(Cl)NiPr2 depending upon the Mg:iPr2NPCl2 mole ratio.

Effect of isopropyl group on phosphorylation of phenols with phosphorous amides

Reaction of resorcinol with phosphorous triamides containing various aliphatic radicals was studied. The preferential cleavage from phosphorus of the diisopropylamino group compared with the less bulky dimethylamino group was observed for the first time. It was shown that resorcinol is easily phosphorylated under mild conditions independent of the nature of substituent on nitrogen, but sterically hindered bulky radicals on nitrogen slow down phenolysis not only of the first, but also of the second amido group.

Spirophosphoranes from the Reaction of Disalicylaldimines with Trivalent Phosphorus Acid Amides

A new approach to the synthesis of spirophosphoranes 9, 11, 15a-c containing P-C, P-O, and P-N intramolecular bonds was developed. It is based on the reaction of trivalent phosphorus acid amides with bis(o-hydroxyaryl)diimines. The composition and structure of the products obtained were confirmed by NMR methods, IR spectroscopy, elemental analysis and X-ray analysis.

Reactions of trisdialkylaminophosphines with acrylohydrazide and imidazolinone derivatives for the synthesis of new organophosphorus derivatives

Trisdimethylaminophosphine reacts with 2-benzamido-N-arylidene-3-aryl- acrylohydrazide to give phosphoryl benzamide and phosphoryl-cyano-benzamide adducts depending on the reaction conditions. Moreover, 1-aryliden-amino-2- phenyl-4-aryliden-2-imidazolin-5-ones react with trisdialkylaminophosphines to yield tetraalkylphosphonic diamide adducts. Possible reaction mechanisms are considered, and the structural assignments are based on analytical and spectroscopic evidence and X-ray analysis. Copyright Taylor & Francis Group, LLC.

Synthesis and Transformation of Glycosyl Azides

Owing to their functional group, glycosyl azides (general structure Glyc-N3) constitute important and versatile derivatives for carbohydrate chemistry. Because of the dipole character of organic azides (see resonance structures A, B, and C) they can function both as nucleophiles and electrophiles, and readily undergo dipolar cycloadditions. Further, as configurationally stable groups, azides are well suited as starting materials for formation of other nitrogen-containing functionalities, such as amines, amides, ureas, carbodiimides, and others.{A figure is presented}. The current article ties in with previous ones that were published in 19611 and 1993.2 In the past decade there have been reports on a number of relevant preparative approaches and uses of anomeric glycosyl azides, which provide a plethora of synthetic options for carbohydrate chemistry.
