  A new approach to the synthesis of 3,6- and 5,6-dialkyl derivatives of 4-hydroxy-2-pyrone. Synthesis of rac-germicidin

  摘要：

  A new approach to the synthesis of 3,6- and 5,6-dialkyl-4-hydroxy-2-pyrones has been developed. The method includes the formation of acylated Meldrum's acids (5-(2-alkyl-3-oxoacyl)-2,2-dimethyl-1,3-dioxane-4,6-diones) followed by their thermal transformation. Introduction of 3-alkyl substituents was accomplished by acylation of 4-hydroxy-2-pyrones and ionic hydrogenation of the 3-acyl derivatives obtained. The effectiveness of this new approach has been demonstrated in the synthesis of rac-germicidin, an autoregulative germination inhibitor of Streptomyces viridochromogenes NRRL B-1551.

  A series of alkylpyrimidine-4,6-diol derivatives were designed and synthesized as novel GRP84 agonists based on a high-throughput screening (HTS) hit 1. 6-Nonylpyridine-2,4-diol was identified as the most potent agonist of GPR84 reported so far, with an EC50 of 0.189 nM. These novel GPR84 agonists will provide valuable tools for the study of the physiological functions of GPR84.

  Lipidic polyketides: We examined the in vitro reactions catalyzed by RpsA, a bacterial type III polyketide synthase (PKS) from Rhodospirillum centenum. RpsA is the first type III PKS shown to be able to efficiently accept two molecules of extender methylmalonyl‐CoA and to synthesize tetraketide compounds through aldol condensation induced by methine proton abstraction.

  DOI：10.1055/s-2001-18759

  日期：——

  A three step procedure for the synthesis of 6-substituted 4-hydroxy-2-pyrones 2 from aldehydes 1 is described. An acetoacetate equivalent 3 was added to the corresponding aldehyde (10 examples) in a vinylogous Mukaiyama aldol addition (72-99%). The intermediate alcohols 4 were oxidized to the ketones 5 using the Dess-Martin method (67%-quant.). A final thermal cyclization of compounds 5 yielded the title compounds 2 (61-92%; 40-85% overall).

  synthesis of the pentaketide flaviolin and its dimeric derivative, and a wide range of pyrones and their coupled derivatives with flaviolin, as well as their halogenated derivatives. The addition of acyl-CoA oxidase to the pathway prior to the polyketide synthase resulted in unsaturated pyrone side chains, further broadening the product spectrum that can be achieved. The approach developed in this work
