    Chemistry of Ti(OiPr)Cl3 with Chloride and Oxygen-Containing Ligands:  The Roles of Alkoxide and Solvents in the Six-Coordinate Titanium Complexes
    摘要:
    Ti((OPr)-Pr-i)Cl-3 reacts easily with various ligands to form a series of six-coordinate complexes, [Ti((OPr)-Pr-i)Cl-5](2-)(HAm+)(2) (Am = NEt(3) (7a) or NC5H5 (7b)), Ti((OPr)-Pr-i)Cl(3)L(2) (L = THF (8) or PhCHO (9)), Ti((OPr)-Pr-i)-Cl-3(PhCHO)(Et(2)O) (10), and [Ti((OPr)-Pr-i)Cl-2(mu-Cl)(PhC(O)OMe)](2) (11). Upon dissolution of 7a in THF, 8 was obtained. When 1 mol equiv of HNEt(3)Cl was added to 8, [Ti((OPr)-Pr-i)Cl-4(THF)](-)(HNEt(3))+ (12) was obtained. With the addition of another 1 mol equiv of HNEt(3)Cl, 12 was converted to 7a. One THF in 8 can be removed in vacuo to give the chloride-bridged dimer [Ti((OPr)-Pr-i)Cl-2(mu-Cl)(THF)](2) (13) which can be converted back to 8 by dissolving in THF. 13 was found to react with 2 mol equiv of HNEt(3)Cl or PhCHO to give 12 and Ti((OPr)-Pr-i)Cl-3(PhCHO)(THF) (14), respectively. The molecular structures of 7b, 8, and 10-13 show short Ti-(OPr)-Pr-i distances, and the relative bonding order of (OPr)-O---Pr-i > Cl-, THF > Et(2)O > PhCHO > mu-Cl- > RC(O)OMe is discussed based on the solid state structures. This bonding sequence is very useful for the prediction of the geometry for six-coordinate complexes of early transition metals with the following principle: The strongest ligand prefers a trans position to the weakest ligand, and the second strongest ligand favors a trans position to the second weakest ligand in the complex. Kinetically, the trans position to the isopropoxide is rather labile for substitution, and the lability of the trans ligand ensures the effectiveness of titanium alkoxides for subsequent reactions or as catalysts in many asymmetric organic syntheses.

    放线菌素内酯的全合成和设计的用于目标识别的光亲和探针
    摘要:
    放线菌内酯是从黄腐放线菌中分离出来的聚酮化合物天然产物家族. 它们对锥虫显示出有效的生物活性,锥虫是被忽视的热带疾病人类非洲锥虫病(昏睡病)和南美锥虫病的病原体,同时对人类细胞系没有细胞毒性。在这里,我们全面介绍了我们合成这种结构独特的 12 元大环内酯类的策略演变,最终以 20 步和 8% 的总产率首次全合成 (+)-actinoallolide A。随后的后期多样化提供了对同类 (+)-actinoallolides B-E 的现成途径。通过这种灵活有效的残局序列,我们还描述了基于放线菌内酯 A 的光亲和探针的设计和合成,以研究其生物作用模式。

    afforded polymers in higher yields and with larger molecular weights than their six-membered ring counterparts. Steric hindrance of the rings was found to significantly affect polymer yields. Increased heterotactic-biased poly(rac-LA) was formed as the number of chlorine atoms increased in TiCl(x)(O-i-Pr)(4)(-)(x). In solution polymerizations, titanium alkoxides catalyzed controlled polymerizations of LA

    A novel strategy for the synthesis of bis(ortho-amine)chelated monoanionic bisaminoaryl−metal complexes is presented. This method constitutes the exchange of a monoanionic, NCN-pincer ligand (NCN = [C6H3(CH2NMe2)2-2,6]-) between a stable arylgold(I) phosphine, [Au(η1-C-NCN)(PPh3)] (2), and a transition metal halide. This transmetalation results in the quantitative formation of [M(NCN)] organometallic
