Hydrophosphination of alkoxyalkenes catalyzed by transition metal complexes

, p. 17 - 22 (2007/10/03)
Diphenylphosphine adds to alkyl vinyl ethers in the presence of Ni(II) and Pd(II) complexes with a high regioselectivity, leading to exclusive formation of the corresponding Markownikoff adducts which were isolated as 1-alkoxyalkyl(diphenyl)phosphine oxid
Catalytic Hydrophosphination of Alkenylalkyl Ethers
Kazankova, Marina A.,Shulyupin, Mstislav O.,Beletskaya, Irina P.
, p. 2155 - 2158 (2007/10/03)
Hydrophosphination of alkenylalkyl ethers catalyzed by Pd- and Ni-complexes is described. The reaction is regioselective giving only Markovnikov product isolated as α-alkoxyalkyldiphenyl oxide after oxidation by H2O2.
WITTIG AND HORNER-WITTIG COUPLING REACTIONS OF 2-SUBSTITUTED CYCLIC ETHERS AND THEIR APPLICATION TO SPIROKETAL SYNTHESIS
Ley, Steven V.,Lygo, Barry,Organ, Helen M.,Wonnacott, Anne
, p. 3825 - 3836 (2007/10/02)
Wittig and Horner-Wittig coupling reactions of tetrahydropyran or tetrahydrofuran 2-triphenylphosphonium salts or 2-diphenylphosphine oxides with aldehydes and lactols affords good yields of the corresponding enol ethers.In selected examples these enol ether products may be further converted to spiroketals some of which are natural pheromones derived from Dacus oleae and Paravespula vulgaris.
A NEW ROUTE TO SPIRO-KETALS USING THE HORNER-WITTING REACTION OF 2-DIPHENYLPHOSPHINOXY CYCLIC ETHERS
Ley, Steven V.,Lygo, Barry
, p. 113 - 116 (2007/10/02)
Two insect pheromones along with other spiro-ketals have been synthesised by a new route which involves Horner-Wittig coupling of 2-diphenylphosphinoxy cyclic ethers with aldehydes and lactols followed by acid catalysed cyclisation.
