Toward the Construction of Enediyne Prodrug Systems Related to the Ring Expanded Artifact Produced Upon Isolation of Maduropeptin Chromophore
摘要:
As part of a modular approach to synthesize maduropeptin analogues of general formula 3, the diacetylene substituted dihydro-1,2-oxazine synthon 13 was constructed via a hetero Diels-Alder reaction between diene 10 and the nitrosodienophile 12. Reductive cleavage of the N-O bond in 13, and acylation of the derived amine 16 gave the stable amide 17. (C) 1997 Published by Elsevier Science Ltd. All rights reserved.

The addition of vinyl and alkynyl Grignard reagents to propargyl alcohols for the direct synthesis of dihydroxydienes and enediyne alcohols from a one pot reaction is described. These products arise from the putative magnesium chelate intermediate 2 upon reaction with the appropriate electrophile. (C) 1999 Elsevier Science Ltd. All rights reserved.
