Organometallic reactions on peptides in aqueous solution. Bottom: HPLC chromatograms of reactions. For each, top panel: starting material used for that reaction, bottom panel: crude HPLC of reaction products. a
a RN′ = Ac-Thr(OtBu)-Tyr(OtBu)-, RC′ = -Asn(Trt)-NHRink-Resin. RN = Ac-Thr-Tyr-, RC = - Asn-NH2.
