  A Novel Palladium-Catalyzed Arylation−Dehydroaromatization Reaction:  Synthesis of 7-Aryltetralones

  摘要：

  A new one-pot room-temperature palladium-catalyzed synthesis of 7-aryltetralones was discovered. This tandem process includes a palladium-catalyzed gamma-selective arylation of the enone 4 followed by a dehydrogenation-aromatization of the initial cross-coupling product.

  of nitrogen-ligated (bis)cationic λ3-iodanes (N-HVIs) for alcohol oxidation and their unprecedented levels of selectivity for the oxidation of equatorial over axial alcohols. The conditions are mild, and the simple pyridine-ligated reagent (Py-HVI) is readily synthesized from commercial PhI(OAc)2 and can be either isolated or generated in situ. Conformational selectivity is demonstrated in both flexible

  复杂多元醇中醇的位点选择性和化学选择性官能化仍然是一个艰巨的合成挑战。尽管在氧中心的选择性衍生化方面已取得重大进展，但化学选择性氧化为相应的羰基的进展却很少。在循环系统中，虽然对轴型醇的选择性氧化是众所周知的，但尚未报道互补的赤道选择性过程。本文中，我们报道了氮连接的（双）阳离子λ3-碘（N-HVIs）在醇氧化中的应用以及它们对赤道醇与轴向醇的氧化选择性的空前水平。条件温和，简单的吡啶连接试剂（Py-HVI）可以很容易地从商业PhI（OAc）2合成，可以分离或原位生成。

  methodology for late-stage natural product derivatization was also demonstrated, providing a new tool for diversity-oriented synthesis and complexity-to-diversity (CTD) efforts. Preliminary mechanistic investigations reveal a strong effect of alcohol conformation on reactive pathway, thus providing a predictive power in the application of this approach to complex molecule synthesis.

• 2-(3-Lithiopropyl)- and 2-(3-lithiopropyl)-2-methyl-1,3-dioxolane: New masked lithium bishomoenolates in the synthesis of bifunctionalized compounds

  日期：——

  2-(3-Lithiopropyl)- and 2-(3-lithiopropyl)-2-methyl-1,3-dioxolane (2) are prepaned by lithiation of the corresponding chlorinated precursors with lithium naphthalenide at −78°C. The reaction of these masked bishomoenolates with different electrophiles yields the expected monoprotected functional carbonyl compounds (3–12), which can be easily deprotected under acid conditions.

• Masked lithium bishomoenolates: useful intermediates in organic synthesis

  The lithiation of the chloro ketals 9 with lithium naphthalenide at -78-degrees-C led to the corresponding masked lithium bishomoenolates 4, which are stable species under these conditions and react with different electrophilic reagents (H2O, D2O, i-PrCHO, PhCHO, MeCOEt, (activated CH2)4CO, (activated CH2)5CO, (activated CH2)7CO, PhCOMe, c-C3H5COPh, PhCN, HCONMe2, PrCO activated N(CH2)4, PhCO activated N(CH2)4, PhCOCl, EtOCOCl, PhCHNPh, and (PhCH2S)2) to give, after hydrolysis with water, the corresponding bifunctionalized compounds 10a-22a, 10b-22b, and 10c-15c. When alkyl halides were used as electrophiles the reaction failed. In the presence of a catalytic amount of the complex CuBr.Me2S, the same reaction with alpha,beta-unsaturated ketones (methyl vinyl ketone or 2-cyclohexanone) yielded the expected products of a 1,4-addition 25a-c and 26b. The deprotection of the masked carbonyl group was easily done by treatment with 2 N hydrochloric acid in THF, so as examples, compounds 27a-29a, 30b, 31b, 32c, and 33c were isolated. The transformation of hemiacetals of the type 27a into substituted tetrahydropyrans was carried out by means of compounds of the type R3SiNu (Nu = H, allyl, CN) in the presence of BF3, so products 34a-41a, 42b, and 43b were prepared. Finally, the in situ oxidation of the deprotected products of the type 27a-arising from the reaction of bishomoenolate 4a with carbonyl compounds-with Jones reagent (for ketones derivatives) or PCC (for aldehydes derivatives) led to the corresponding delta-lactones 44-57.
