Second generation grubbs catalyst
WebFinally, RCM was assayed with second-generation Grubbs catalyst (0.2 eq) at 40ºC for 18 h in the presence of LiCl to minimize aggregation. However, HPLC analysis of an aliquot 35 of resin-cleaved, deprotected peptides (TFA/TIS/H 2O 95:2.5:2.5) revealed that only 56% of the linear peptide had been cyclised.
