Imide-amide rearrangement of cyclic phosphorimidates: A mechanistic study

Studies aimed at the development of new synthetic pathways for the preparation of chiral cyclic oxaza and diaza phosphoramides suitable for use in asymmetric chemistry led us to the investigation of the imide-amide rearrangement of cyclic phosphorimidates

Nature of acid-catalyzed alcoholysis of amides of trivalent-phosphorus acids

To study the chemical nature of the acid catalysis of amides of trivalent-phosphorus acids (ATPA) alcoholysis the most important procedural problems have been solved. Simple and efficacious techniques for the purification of original ATPA from amine hydrohalides have been worked out. A precise and reliable way has been chosen to control the residual amount of amine hydrohalides in ATPA having been subjected to the various purification procedures. The nature of the dependence of alcoholysis rate constants for ATPA of different structures on the amine-hydrohalide concentration has been established. The general acid catalysis was established using the Bronsted equation, so that the process includes the formation of a catalytic H-complex incorporating substrate and catalyst on the whole. Amides P(III) of different types treated with anhydrous hydroborofluoric acid readily from the corresponding P-protonated salts. The conversions of corresponding products of complete protonation have been investigated. The structure of P-protonated salt 23 has been studied by means of X-ray analysis.

Conformation and Stereodynamics of 2-Dialkylamino-1,3-dioxa- and 3-Methyl-1,3-oxaza-2-phospholanes. A Carbon-13 Nuclear Magnetic Resonance and Theoratical MNDO Investigation.

Rotation around the exocyclic P-NR2 bond in the title compounds (R = Me, Et, and i-Pr) has been frozen on the 13C n.m.r. time-scale at -100 to -150 deg C.The exocyclic PNC coupling constants confirm that the preferred conformation has one NR group eclipsing the phosphorus lone pair and the other lying over the face of the ring; this geometry is also supported by MNDO SCF MO calculations.The P-NR2 rotational barriers, which lie in the range 6.0-9.2 kcal/mol, increase in the sequence 1,3-dioxa- 1,3-oxaza- 1,3-diazaphospholane and also with increasing size of the NR group.MNDO calculations of the barrier height reproduce the former sequence.The cyclic POC and PNC coupling constants are discussed in relation to the ring conformation, and some 15N n.m.r. data are reported.
