Palladium-catalysed reaction of unprotected 2-, 3-, and 4-iodophenols with a range of amino acid derived organozinc reagents (not used in excess) gives the expected products in good to excellent yield, demonstrating that carbon-zinc bonds are not protonated by acidic phenols under the conditions of palladium-catalysed coupling reactions.

The need for new therapies to treat systemic fungal infections continues to rise. Naturally occurring hexapeptide echinocandin B (1) has shown potent antifungal activity via its inhibition of the synthesis of β-1,3 glucan, a key fungal cell wall component. Although this series of agents has been limited thus far based on their physicochemical characteristics, we have found that the synthesis of analogues bearing an aminoproline residue in the 'northwest' position imparts greatly improved water solubility (>5 mg/mL). The synthesis and structure-activity relationships (SAR) based on whole cell and upon in vivo activity of the series of compounds are reported. Copyright (C) 2000 Elsevier Science Ltd.
