  Synthesis and Applications of Tetrahydrofuran-Stable Substituted (3-Lithioxyalkyl)- and (4-Lithioxyalkyl)lithiums, Modified with Magnesium 2-Ethoxyethoxide

  摘要：

  Substituted hydroxyalkyl phenyl sulfides 3 have been synthesized from the corresponding allylic or homoallylic alcohols 2. Regiospecific cleavage of the C-SPh bond of the sulfides 3 by lithium dispersion in tetrahydrofuran (THF) led to the synthesis of substituted (3-lithioxyalkyl)- and (4-lithioxyalkyl)lithiums 4, most of which share the omega carbon with a carbocyclic ring. The organolithiums were modified with magnesium 2-ethoxyethoxide in order to suppress their reactivity toward THF cleavage, thus offering the advantage of preparing storable ethereal solutions of certain types of (lithioxyalkyl)lithiums. This strategy appears to be of rather broad scope. The functionalized organolithiums prepared in this way react normally with electrophilic reagents with yields in the range 35-55%. Thus, carboxylations of 4 yielded lactones 5, some of which are natural products, while reactions of 4 with benzophenone and cyclic ketones yielded 1,4- and 1,5-diols 6 and 7, respectively.

  当立体化学模型无法使用时，烯丙基镁试剂对 α-取代酮的非对映选择性添加

  摘要：

  烯丙基镁试剂与手性酮反应的立体选择性不能用立体化学模型轻易解释。竞争实验表明，络合步骤是不可逆的，因此亲核试剂无法获得最广泛的可能遭遇络合物，因此无法使用可用模型轻松分析。然而，向酮中添加烯丙基镁试剂仍然可以是立体选择性的，前提是羰基采用的构象会导致一个面被完全阻止与烯丙基镁试剂的接近。

  A ball-milling-enabled zinc-mediated Barbier-type allylation reaction is reported. Notably, running the reaction in this manner renders it effective irrespective of the initial morphology of the zinc metal. The process is operationally simple, does not require inert atmospheres or dry solvents, and is reported over a range of aldehyde and ketone substrates; a gram-scale process is demonstrated.

  of α‐methylene‐γ‐lactones through the palladium(II)‐catalyzed lactonization of homoallylic alcohols with alkynamides has been reported. The hydroxyl group in the terminal olefins cooperates with the amide in alkynamides to promote the cyclization by suppressing the β‐H elimination. This process provides a route to construct naturally occurring biologically multifunctional α‐methylene‐γ‐lactones.

  据报道，通过钯（II）催化均烯丙基醇与炔酰胺的内酯化，可以方便高效地合成α-亚甲基-γ-内酯。末端烯烃中的羟基与炔基酰胺中的酰胺协同作用，通过抑制β-H的消除来促进环化。该过程提供了构建天然存在的生物多功能α-亚甲基-γ-内酯的途径。

  A conceptually novel approach is described for the synthesis of six‐membered cyclic carbonates derived from carbon dioxide. The approach utilizes homoallylic precursors that are converted into five‐membered cyclic carbonates having a β‐positioned alcohol group in one of the ring substituents. The activation of the pendent alcohol group through an N‐heterocyclic base allows equilibration towards a thermodynamically

  aldehydes and ketones followed by O-allylation of the obtained carbinols gave the corresponding allyl or homoallyl ethers, respectively. Ring-closing metathesis of these compounds afforded in many cases cyclic ethers (dihydrofurans and dihydropyrans, respectively) bearing disubstituted and trisubstituted CC bonds. These were then subjected to allylic oxidation to yield conjugated γ- and δ-lactones. Reasons
