  4-(dimethylamino)pyridine. A similar reaction occurs with triethylamine when using a catalytic amount of 4-(dimethylamino)pyridine 1-oxide as an effective promoter for the intramolecular condensation reaction. These methods are successfully applied to the synthesis of erythro-aleuritic acid lactone and an eight-membered-ring lactone moiety of octalactins A and B. The efficiency of the cyclizations is

  使用2-甲基-6-硝基苯甲酸酐和三乙胺，通过促进碱性催化剂（例如4-（二甲基氨基）吡啶），由几乎等摩尔量的羧酸和醇在室温下以高收率和高化学选择性获得各种羧酸酯。在4-（二甲基氨基）吡啶存在下，使用2-甲基-6-硝基苯甲酸酐，在室温下由相应的ω-羟基羧酸高产率地制备了多种内酯。当使用催化量的4-（二甲基氨基）吡啶1-氧化物作为分子内缩合反应的有效促进剂时，三乙胺也会发生类似的反应。这些方法已成功应用于赤藓红的合成-八聚肌动蛋白A和B的八聚环戊二酸酯内酯和一个八元环内酯部分。将环化的效率与其他报道的内酯化的效率进行了比较。

  Herein, we report the semisynthetic production of the potent transient receptor potential canonical (TRPC) channel agonist englerin A (EA), using guaia 6,10(14)-diene as the starting ma-terial. Guaia-6,10(14)-diene was systematically engineered in Escherichia coli and Saccharomyces cerevisiae using the CRISPR/Cas9 system and produced with high titers. This opened the possibility for a very short semisynthesis

  在此，我们报告了使用愈创木 6,10(14)-二烯作为起始材料的强效瞬时受体电位规范 (TRPC) 通道激动剂 englerin A (EA) 的半合成生产。Guaia-6,10(14)-二烯使用 CRISPR/Cas9 系统在大肠杆菌和酿酒酵母中系统工程化，并以高滴度生产。这为 EA 和两种相关愈创木酚和东方香酚 E 的非常短的半合成开辟了可能性。潜在的可扩展方法结合了合成生物学和化学合成的优势，并提供了一种生产 EA 及其类似物的有效且经济的方法。

  ingredient of catmint, was selected as starting material for the first enantioselective synthesis of englerin A. This cytotoxic guaiane sesquiterpene is a highly selective inhibitor (1–87 nM) of several renal cancer cell lines. The absolute configuration of this natural product was determined by total synthesis.

• Total Synthesis and Structural Elucidation of the Antifungal Agent Papulacandin D

  日期：1996.1.1

  Condensation of the aryllithium reagents, prepared from the bromides 10 and 11 and tert-butyllithium, with lactone 19 and acid-catalyzed spirocyclization gave the papulacandin spiroketals 14 and 15. Subsequent protection using di-tert-butylsilyl bis(trifluoromethanesulfonate) gave the diols 31 and 30. Isoleucine (37) was converted using a double Wittig reaction sequence and propargylation of the intermediate aldehyde 46 into the alkynol 47. Separation of the C-7 epimers of 47 was achieved using kinetic resolution via Sharpless epoxidation. Both alkynol epimers 53 and 57 were converted into the papulacandin side chain esters 65 and 66 using a hydrozirconation and palladium(0)-catalyzed coupling sequence. Comparisons of Mosher ester derivatives of 65 and 66 with the Mosher ester derivative of the natural papulacandin side chain and further degradation were consistent with the stereochemistry of the natural product being 7S,14S. Esterification of the spiroketals with the mixed anhydride 70 and global deprotection gave papulacandin D (1).
