Tris(triphenylphosphine)Rhodium(1) Chloride in the presence trialkyl p
hosphine catalyses the isomerization of hydroxy alkynes to unsaturated
trans keto and hydroxy esters depending on the nature of the phosphin
e. Dipeptide isosters were obtained in a an efficient manner by the ap
plication of this methodology.
