  Ring-Closing Metathesis in the Synthesis of Large and Medium-Sized Oxacycles. Application to the Synthesis of Polyoxygenated Macrocycles

  摘要：

  Ring-closing olefin metathesis (RCM) catalyzed by Grubbs's ruthenium benzylidene complex 1 is applied to the synthesis of unsaturated rings ranging in size from seven to thirteen members in trans-fused polyether systems. Reaction occurs with great efficiency in the cyclization of oxepene and oxocene rings, but as ring size increases, yields drop. The influence of the final double bond position is also studied. Better yields and milder reaction conditions are observed when an additional oxygen atom is introduced on the diene. This feature has promoted the application of this reaction to the synthesis of polyoxygenated macrocycles (with sizes ranging from 15 to 21 members), with excellent results.

  An efficient and convenient method for the synthesis of sugar-lactam conjugates is reported starting from readily available sugar azides using the Aubé reaction. Cyclic azido alcohols are used in the Aubé reaction for the first time in a carbohydrate setting. The resulting glycoconjugates could be further used to increase the chemical diversity on the sugar backbone, and may find potential applications as glycomimetics, peptidomimetics, in glycotargeting and in CNS drug delivery.

  A single, unified convergent strategy for the stereocontrolled synthesis of trans-fused polyethers was developed. It was demonstrated that the epimerization and reductive intramolecular coupling of hydroxy ketones in reactions with silane-Lewis acids (SI-LA) to generate ethers in C-linked oxacycles is affected by its conformational preference in a predictable manner. The obtained results make evident
