Transesterification, ester linkers

Transesterification of ester linkers can be conducted by many protocols. Scheme 11 gives a short overview illustrating the most popular procedures for a transesterification into methylesters [ 113,114]. [Pg.15]

Transesterification of resin-bound esters to give thioesters is also a ht-erature known procedure. Swinnen et al. released thioesters from sohd-supported esters by addition of ethanethiol and Me2AlCl (in situ formation of alkylaluminum thiolate) [115]. This strategy does not afford special linkers and can be performed for example on Wang or PAM resins. The reaction sequence favors side reaction of the ester species to thio-orthoesters and ketene thio acetals that could be transformed into the desired thioesters via treatment with TFA. [Pg.15]
