α- and β-diphenylphosphorylated secondary alkanols: I. general method of synthesis and extraction properties towards f-elements
Goryunov,Matveeva,Safiulina,Goryunova,Bodrin,Brel
, p. 629 - 638 (2016/06/01)
A simple and effective general method of synthesis of α- and β-diphenylphosphorylated secondary alkanols by the reduction of the corresponding phosphorylalkanones with NaBH4 was developed. The extraction properties of the resulting phosphorylalkanols Phs
Intramolecular hydroboration of unsaturated phosphine boranes
Shapland, Peter,Vedejs, Edwin
, p. 4094 - 4100 (2007/10/03)
Homoallylic phosphine boranes undergo intramolecular hydroboration upon activation by triflic acid. The reaction occurs via an intermediate B- trifluorosulfonyloxyborane complex such as 15, followed by SN1-like or SN2-like displaceme
A mechanistic alternative for the intramolecular hydroboration of homoallylic amine and phosphine borane complexes
Scheideman, Matthew,Shapland, Peter,Vedejs, Edwin

Intramolecular hydroboration is demonstrated starting from homoallylic amine boranes upon activation by iodine. The process involves a B-iodoborane complex as the intermediate and may occur via internal displacement of iodide by the alkene to generate a cationic borane-alkene π-complex on the way to hydroboration products. The reaction can be carried out using a catalytic amount of iodine. Copyright
Et3B-induced radical addition of diphenylphosphine oxide to unsaturated compounds
Rey, Patrick,Taillades, Jacques,Rossi, Jean Christophe,Gros, Georges
, p. 6169 - 6171 (2007/10/03)
Et3B-catalysed addition of diphenylphosphine oxide to unsaturated compounds, alkenes, unsaturated acids, allylic alcohols, and allylic α-O-acetyl nitriles constitutes a practical route to a variety of functionalized diphenylphosphine oxides. Th
EXTENSION OF THE HORNER-WITTIG REACTION TO THE SYNTHESIS OF E-ALKENES WITH CHIRAL SUBSTITUENTS: STEREOCHEMICAL CONTROL BY ACYL TRANSFER
Ayrey, Peter M.,Warren, Stuart
, p. 4581 - 4584 (2007/10/02)
Single crystalline diastereoisomers of hydroxyalkyl phosphine oxides (and hence functionalised E-alkenes) can be isolated, even when other chiral centres are present in the molecule, if they are made by acyl transfer.
ACYL TRANSFER REACTIONS WITH PHOSPHINE OXIDES: SYNTHESIS OF E-HOMOALLYLIC ALCOHOLS, CYCLOPROPYL KETONES, AND γ-HYDROXY KETONES
Wallace, Paul,Warren, Stuart
, p. 2971 - 2978 (2007/10/02)
Esters of 3-hydroxypropylphosphine oxides rearrange in base by O to C acyl (RCO) transfer to give the hydroxy ketones (8). threo-Selective reduction of (8) leads to pure E-homoallylic alcohols whilst C to O acyl )Ph2PO) transfer leads to γ-hydroxy ketones with nucleophilic aqueous base or cyclopropyl ketones with BuOKt - HOBut.
SYNTHESIS OF E-HOMOALLYLIC ALCOHOLS, γ-HYDROXYKETONES, AND CYCLOPROPYL KETONES FROM 3-DIPHENYLPHOSPHINOYL (Ph2PO) PROPANOLS BY ACYL TRANSFER
Wallace, Paul,Warren, Stuart
, p. 5713 - 5716 (2007/10/02)
Carboxyl transfer (O*C) on 3-Ph2PO propyl esters (9) gives an intermediate (10) from which the Ph2PO group may be removed by the Horner-Witting reaction or by Ph2PO transfer (C*O) to give the title compounds.
