Diphenylphosphinoyl lactones in the control of remote stereochemistry
Mitchell, Helen J.,Warren, Stuart
, p. 2105 - 2108 (2007/10/03)
E-alkenes with three stereogenic centres related 1,4- and 1,5- across the double bond can be prepared with good stereoselectivity from 3-diphenylphosphinoyl-4-alkenyl butyrolactones by alkylation, epoxidation, epoxide opening by a nucleophile, reduction a
Structure and Conformation of α'-Diphenylphosphinoyl Enones: X-Ray Structure of E-(5SR,6SR)-3,6-Dimethyl-5-diphenylphosphinoyl-7-triphenylmethoxyhept-2-en-4-one
Doyle, Michael J.,Hall, David,Raithby, Paul R.,Skelton, Nicholas,Warren, Stuart
, p. 517 - 524 (2007/10/02)
A series of α'-diphenylphosphinoyl enones has been prepared and their s-cis or s-trans conformations correlated with 1H NMR and IR spectra and an X-ray crystal structure of the title compound.The effect of chelation to cerium(III) is correlated with the r
The Synthesis of δ-Hydroxy Allylic Phosphine Oxides by Palladium(II)-catalysed Allylic Acetate Transposition
Clayden, Jonathan,Warren, Stuart
, p. 2913 - 2924 (2007/10/02)
Palladium(II)-catalysed allylic acetate transposition, when driven by the diphenylphosphinoyl (Ph2PO) group, is regiospecific (acetate moves away from the Ph2PO group), stereoselective (the new double bond is E), and stereospecific (the acetate moves supr
The Synthesis of δ-Hydroxy Allylic Phosphine Oxides by Palladium(II)-Catalysed Allylic Transposition
Clayden, Jonathan,Collington, Eric W.,Warren, Stuart
, p. 7039 - 7042 (2007/10/02)
Palladium(II)-catalysed rearrangement of allylic acetates 5, which contain a diphenylphosphinoyl group, yields transposed acetates 6 in good yield.The reaction is mild, general for most substitution patterns, and stereospecific.The transposed acetates 6 m
