2-Biotinyl- and 2-hexanoyldimedone were prepared in a simple one step high yielding process by acylation of dimedone with biotin and hexanoic acid respectively, then without activation each attached to the N-terminus of resin-bound peptides. Following acidolytic side-chain deprotection and concomitant cleavage of the tagged peptides from the support, affinity purification was achieved on an avidin-agarose column and by RP-HPLC respectively. The purified peptides were finally released from the tag with 5% aqueous hydrazine. (C) 1997 Elsevier Science Ltd.
