A new approach to the simultaneous chemical synthesis of large numbers of different peptide sequences is described.1 The particular features of the method presented2 are: - cellulose paper discs serve as solid supports for Individual peptide sequences, - the peptide chains are linked to the cellulose via a p-alkoxybenzyl ester anchor cleavable by mild treatment with trifluoroacetic acid in dichloromethane

A broad variety of new acyclic vinyl ethers (see 6–41) have been synthesized via the vinyl-interchange reaction of ethyl vinyl ether at room temperature using mercury(II) trifluoroacetate as a highly efficient catalyst. The appropriate vinyl ethers were reacted under acidic conditions with 3′,5′-O-silyl-protected uridine 42 to the corresponding 2′-O-(1-alkoxyethyl) derivatives 43–83 which gave, on
