Reacting ethoxycarbonyl triphenyl phosphorane with activated alkylhalides in chloroform gave the ylides 4 - 12. They react smoothly and in general without racemisation with α-amino aldehydes resulting in the dipeptide mimetics 15 - 25. Exceptions are the
Olefin-Directed Palladium-Catalyzed Regio- and Stereoselective Oxidative Arylation of Allenes

, p. 9066 - 9069 (2015)
An olefin-directed palladium-catalyzed oxidative regio- and stereoselective arylation of allenes to afford 1,3,6-trienes has been established. A number of functionalized allenes, including 2,3- and 3,4-dienoates and 3,4-dienol derivatives, have been inves

Various alkylidenephthalides (E- and Z-5, 6 and 7) were prepared by Wittig reaction of phosphoranes 4a, 4b and 4c respectively with phthalic anhydride.The products were then lactonised, using chloro(trimethyl)silane and sodium iodide, to the corresponding
