in the C-2 position of the oxazolidine/thiazolidine ring system, this protection technique is adaptable to all common strategies in peptide synthesis. We describe new types of ΨPro building blocks suitable for standard Fmoc/tBu-based solidphase peptide synthesis, convergent strategies, and chemoselective ligation techniques as well as their use as a structure-disrupting, solubilizing protection technique

Commercially available Fmoc-protected L-amino acids were employed and coupled to L-allylglycine. Cross metathesis with 2-methyl-2-butene using second generation Grubbs' catalyst gave L-prenylglycine-containing dipeptides. Treatment with trifluoromethanesulfonic acid resulted in cyclisation and subsequent formation of acid-stable 5,5-dimethyl-L-proline dipeptides for direct insertion into linear peptide sequences.

The Fmoc/TAEA and Bsmoc/TAEA methods for the rapid, continuous solution synthesis of peptide segments are shown to be applicable to the gram-scale synthesis of short peptides as well as, for the first time, to the synthesis of a relatively long (22-mer) segment, (hPTH 13-34). In the latter case the crude product was of significantly greater purity than a sample obtained via a solid-phase protocol. The Bsmoc methodology was optimized by a new technique involving filtration of the growing partially deprotected peptide at each coupling-deprotection cycle through a short column of silica gel.
