• Synthetic Studies of Antitumor Macrolide Rhizoxin:  Stereoselective Syntheses of the C(1)−C(9) and C(12)−C(26) Subunits

  Horner-Wadsworth-Emmons reaction. The central segment 4 and the oxazole chromophore side chain 3 were coupled using another highly stereoselective Horner-Wadsworth-Emmons reaction. Two different lactone subunits [C(1)-C(9) segment 5 and C(3)-C(10) segment 47] were also prepared, employing a thermodynamically controlled diastereotopic group differentiation tactic for establishing the C(5) stereochemistry

  描述了一种三重收敛的合成方法，该方法最终完成了大环内酯类抗肿瘤剂Rhizoxin的C（1）-C（9）和C（12）-C（26）亚基的对映选择性合成。中央C（12）-C（20）亚基4是通过猪胰脂肪酶的非对映选择性酶促乙酸15水解，螯合控制的爱尔兰-克莱森重排（10-> 12）结合动力学溴化（12）有效制备的（12） -> 14）和Mitsunobu反演（23-> 26），以引入三个连续的C（15）-C（17）立体中心。C（18）-C（19）三取代（E）-烯烃的形成是通过立体选择性Horner-Wadsworth-Emmons反应实现的。使用另一个高度立体选择性的霍纳-沃兹沃思-埃蒙斯反应将中心链段4和恶唑生色团侧链3偶联。
• Selective Lithiation of 2-Methyloxazoles. Applications to Pivotal Bond Constructions in the Phorboxazole Nucleus
  作者：David A. Evans、Victor J. Cee、Thomas E. Smith、Keith J. Santiago

  DOI：10.1021/ol990027r

  日期：1999.7.1

  The lithiation of 2-methyloxazoles with alkyllithium and hindered lithium amide bases generally results in the competitive formation of a mixture of 5-lithio- and 2-(lithiomethyl)oxazole isomers. Herein a synthetically useful lithiation method which allows for the selective formation of 2-(lithiomethyl)oxazole is described. Diethylamine has been found to be a kinetically competent proton source that will mediate the equilibration of the kinetically formed 5-lithiooxazole to its more stable 2-(lithiomethyl)oxazole counterpart. Application of this metalation strategy with lithium diethylamide to two important bond constructions relevant to a projected phorboxazole synthesis is presented.
