[reaction: see text] We describe a new approach for the solid-phase synthesis of indoles 1 that involves a one-pot release and cyclization reaction of a solid-supported hydrazone through a Wang-type linker. Using this solid-phase methodology, we accomplished the synthesis of 40 naltrindole derivatives.

Highly selective nonpeptide ligands with potent deltaopioidreceptorantagonist activity have been developed using the message-addressconcept. This approach envisaged the deltaopioidreceptor to contain two major recognition subsites; a message subsite which recognizes the pharmacophore, and an address subsite that is unique for the deltareceptor type and confers selectivity. The message and address
