Acyclic internal alkenes are a class of challenging substrates in asymmetric Heck-type reactions due to difficulties related to both reactivity and selectivity control. Employing acyclic alkenyl alcohols, an asymmetric Heck–Matsuda reaction is developed through the strategy of chiral anion phase transfer. Various chiral ketones could be obtained in high levels of enantioselectivity. A catalytic amount

Mitsunobu's method of acetoaceticesteralkylation by -nitrophenyl-ethanol avoid the SRN1 reaction and is well appropriate for the correlation of absolute configuration and of the O and C alkylation products.
