โœฆ Synopsis


A mild and efticient method to obtaia fully t-&tyl type protected alcohols based on the alkylation of Fmoc amino alcohols with the "polymeric dipheayldiazomethane" 1 followed by StanQrd Fmoc solid phase synthesis is presented. The resulting pepidyl benzhydryl ethers 3 can he cleaved with 1 -2% trlfluoroac&c acid in methylene chloride to yield the protected peptide alcohols.

Boc/'Z-protected PNA oligomers were synthesised on solid phase. The use of the allylic HYCRON resin allowed for the application of both Boc-and Fmoc-protecting groups. Highest yields were obtained when the monomeric building block was synthesised on solid phase rather than loaded as preformed unit.
