Studies directed toward the synthesis of viridenomycin. Route 2: a second generation approach
摘要:
A second generation approach toward the synthesis of viridenomycin is described. Three key fragments of the molecule have been synthesized in stereochemically pure form. Initial studies toward the coupling of these fragments with the aim of assembling the macrocycle are detailed. Final efforts to reach the title compound are documented. (C) 2001 Elsevier Science Ltd.

realize transition-metal-catalyzed enantioselective C–O bond constructions via hydrofunctionalization of conjugated dienes. Here, we perform a comprehensive studytoward the stereoselective formal hydration and hydroaminoxylation of conjugated dienes by synthesizing a set of new P,N-ligands and identifying an aryl-derived oxime as a surrogate for both water and hydroxylamine.

This paper describes a diamination process using di-t-butyldiaziridinone as nitrogen source and N-heterocyclic carbene−Pd(0) complex as catalyst. A wide variety of conjugated dienes and trienes can be effectively diaminated in good yields with high regio- and stereoselectivities.
