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.
SYNTHESIS OF SINGLE ISOMERS (E OR Z) OF UNSATURATED ALCOHOLS BY THE HORNER-WITTIG REACTION
Buss, Antony D,Greeves, Nicholas,Levin, Daniel,Wallace, Paul,Warren, Stuart
, p. 357 - 360 (2007/10/02)
Single isomers (E or Z) of homoallylic and higher alcohols can be synthesised from ω-hydroxyalkyldiphenylphosphine oxides and aldehydes, or from alkyldiphenylphosphine oxides and lactones
