  Determination of the Relative and Absolute Stereochemistry of Fostriecin (CI-920)

  摘要：

  The absolute stereochemistry of fostriecin (1, CI-920), a potent antitumor antibiotic presently in Phase I clinical trials at NCI, was determined to be 5R,8R,9R,11R. 2D H-1-H-1 NMR. NOE experiments conducted on the cyclic phosphate derivative 2 and acetonide revealed a syn-diol stereochemical relationship between C8 and C9 and an anti-diol stereochemical relationship between C9 and C11, respectively. The 5R absolute configuration assignment was confirmed by synthesis of the degradation product 8 previously disclosed. Additional degradation studies of 1 to provide 7 and chiral-phase HPLC comparison with a sample of known chirality established the absolute stereochemistry of C11 to be R. This, along with the relative stereochemical assignments established the full set of absolute stereochemistry assignments for 1.

  日期：——

  Total synthesis of (+)-anamarine a polyoxygenated δ-pyranone natural product was accomplished via cross-metathesis protocol starting from 3-butene-1-ol and glycidol. Other key features of this synthetic strategy include use of Sharpless asymmetric epoxidation, dihydroxylation, and deoxygenation-isomerization through allene rearrangement.

  (+)-安玛琳的全合成是一种多氧化的δ-吡喃酮天然产品，采用交叉美克斯法从3-丁烯-1-醇和环氧醇出发实现。该合成策略的其他关键特点包括使用Sharpless不对称环氧化、二羟基化以及通过全烯重排进行去氧化-异构化。

  The first total synthesis of the potent antitumor agent fostriecin (CI-920) is described, confirming the relative and absolute stereochemistry assignments. Fostriecin is a unique phosphate monoester which exhibits weak topoisomerase II inhibition (IC50 = 40 μM) and more potent and selective protein phosphatase 2A and 4 (PP2A and PP4) inhibition (IC50 = 40−3 nM and 1.5 nM), resulting in mitotic entry

  描述了强效抗肿瘤剂 fostriecin (CI-920) 的首次全合成，确认了相对和绝对立体化学分配。Fostriecin 是一种独特的磷酸单酯，表现出弱拓扑异构酶 II 抑制 (IC50 = 40 μM) 和更有效和选择性的蛋白磷酸酶 2A 和 4（PP2A 和 PP4）抑制（IC50 = 40-3 nM 和 1.5 nM），导致有丝分裂进入检查点抑制。由于在天然衍生材料的储存过程中观察到药物稳定性问题，甚至在达到治疗浓度或确定剂量限制毒性之前，使用 Festriecin 的 I 期临床试验是第一个探索这种新作用机制的潜力的试验。
• Two simple and alternative approaches for the synthesis of anticancer active goniothalamin

  Two alternative and straightforward routes were developed for the construction of (R)-goniothalamin, a natural anticancer agent. The first method starts with (R)-glycidol involving stereoselective (partial) reduction of alkyne and sulfoxide Julia-Lythgoe olefination as key steps. Second method deals with the synthesis of (R)goniothalamin from 2,3-O-isopropylidene-D-glyceraldehyde with partial reduction

  为构建 (R)-goniothalamin（一种天然抗癌剂）开发了两种替代且直接的途径。第一种方法从 (R)-缩水甘油开始，包括炔烃和亚砜 Julia-Lythgoe 烯化的立体选择性（部分）还原作为关键步骤。第二种方法涉及从 2,3-O-异亚丙基-D-甘油醛合成 (R)goniothalamin，其中部分还原腈和 Still-Gennari 立体选择性烯化作为关键步骤。这两种标准有机反应顺序简单的方法可用于有机化学二、三年级课程。

  The total syntheses of (R)-goniothalamin (1), a styryl lactone isolated from several Goniothalamus species, via catalytic asymmetric allylation of alpha-benzyloxyacetaldehyde (2), followed by ring-closing metathesis and Wittig olefination and via catalytic asymmetric allylation of trans-cinnamaldehyde (12), followed by ring-closing metathesis are reported. The anti proliferative activities of (R)-1 and its Z-isomer 10 as well as of the synthetic dihydropyranone intermediates 7 and 8 against eight different cancer cell lines are also described.
