Copper-catalyzed allylic C-H phosphonation
Yang, Bin,Zhang, Hong-Yu,Yang, Shang-Dong
supporting information, p. 3561 - 3565 (2015/03/30)
An efficient copper-catalyzed allylic C-H phosphonation reaction has been developed under mild reaction conditions. This method exhibits high regioselectivity and stereoselectivity. Various alkenes with useful functional groups are compatible in this tran
Stereoselective Acyl Transfer Reactions controlled by the Diphenylphosphinoyl Group: X-ray Structures of Stable Crystalline Silylated Tetrahedral Intermediates
Feeder, Neil,Hutton, Gordon,Warren, Stuart
, p. 5911 - 5914 (2007/10/02)
Acyl transfer with LDA on benzoates of single diastereoisomers of 3-hydroxyalkyldiphenylphosphine oxides in the presence of trimethylsilyl chloride gives silylated tetrahedral intermediates in carbonyl displacement reactions with the stereochemically cont
STEREOCHEMICALLY CONTROLLED SYNTHESIS OF UNSATURATED ACIDS VIA DIPHENYLPHOSPHINOYL(Ph2PO)-KETOACIDS
Levin, Daniel,Warren, Stuart
, p. 505 - 508 (2007/10/02)
Acylation of phosphine oxide anions with derivatives of cyclic anhydrides or oxidative cleavage of cyclic allyl phosphine oxides gives Ph2PO-ketoacids: reduction, separation of diastereoisomers, and completion of the Horner-Wittig reaction gives single isomers (E or Z) of unsaturated acids.
Synthesis of an Unstable Allyl Sulphide from an Allyl Phosphine Oxide
Torr, Richard S.,Warren, Stuart
, p. 1169 - 1172 (2007/10/02)
The epoxide (8) reacts with PhSLi to give Horner-Wittig intermediate (9) and hence the allyl sulphide (10).The stereochemistry and reactions of the intermediates are described.
Synthesis of β-(Diphenylphosphinoyl) Ketones
Bell, Andrew,Davidson, Alan H.,Earnshaw, Chris,Norrish, Howard K.,Torr, Richard S.,et al.
, p. 2879 - 2892 (2007/10/02)
The title compounds may be made by addition of phosphorus nucleophiles (Ph2PO-, Ph2POMgX, Ph2PCl) to enones, by addition of phosphorus-stabilised carbanions to a α-carbonyl cation equivalents (2,3-dichloropropene, epoxides, and α-MeO-ketones) and by oxidation of allyl diphenylphosphine oxides.
STARKE ERLEICHTERUNG DER CARBONYLOLEFINIERUNG MIT ORGANOSCHWERMETALLREAGENZIEN DURCH EINE DIPHENYLPHOSPHORYLGRUPPE IM REAGENZ
Tilhard, Hans-Joachim,Ahlers, Holger,Kauffmann, Thomas
, p. 2803 - 2806 (2007/10/02)
Carbonyl olefination with a lithiomethane, having besides the group -P(O)Ph2 at the methane C-atom an organo-heavy-metal group, occurs at low temperatures to give exclusively diphenylphosphoryl substituted olefins.
