  摘要：

  When treated with KOH under phase-transfer catalysis or with (BuOK)-O-t, 3-substituted (alkyl or phenyl) 1, 1, 3-tribromo-1-fluoropropanes 1a-c exclusively generate previously unknown (alk-1-ynyl)fluorocarbenes 5a-c, which react with olefins to give 1-(alk-1-ynyl)-1-fluorocyclopropanes 6a-h in 12-69% yields. Under analogous conditions, 3-alkyl- and 3-aryl-3-bromo-1, 1, 1-trichloropropanes 2a-c selectively afford (alk-1-ynyl)chlorocarbenes 7a-c, which are trapped by olefins to form the corresponding 1-(alk-1-ynyl)-1-chlorocyclopropanes 8a-k in 35-70% yields. (Phenylethynyl)chlorocarbene 7a is also selectively generated from 1, 1, 1, 3-tetrachloro-3-phenylpropane (3a) upon its treatment with (BuOK)-O-t. With an excess of 2,3-dimethylbut-2-ene or 2-methylpropene, carbene 7a yields 1-chloro-1-(phenylethynyl)cyclopropanes 8a or 8c, respectively. In contrast, 1, 1, 1, 3-tetrachloroheptane 3b and 3-alkyl- and 3-phenyl-1, 1, 1, 3-tetrabromopropanes 4a,c,f react with bases in the presence of olefins to give, along with the corresponding 1-(alk-1-ynyl)-1-halocyclopropanes 8a,c,d and 11a-f, vinylidenecyclopropanes 12a,c-g, which suggests the generation, under these conditions; both (alk-1-ynyl)halocarbenes 7b and 9a-c and vinylidenecarbenes 10 and 11a-c. The composition and structures of intermediate products in the reactions of tetrahalides 1b, 2a, 2b, 3a, and 3b with (BuOK)-O-t were determined and the mechanisms for carbene generation in these reactions were proposed.

  铜催化的二氯基质的丙炔基取代：三取代烯的对映选择性合成和丙炔季铵立体中心的形成。

  摘要：

  提出了一种简单而通用的铜催化的炔丙基取代过程。使用容易制备的前手性二氯底物，易于获得的格利雅试剂以及催化量的铜盐和手性配体，我们获得了一系列合成上令人感兴趣的三取代氯代烯。底物范围和亲核试剂范围广泛，可为所需的1,3取代产物提供较高的对映选择性。通过铜催化的对映体特异性1,1 / 1,3取代基，可以将对映体富集的氯丙二烯进一步转化为带有全碳四元立体异构中心的相应三取代的丙二烯或末端炔。

  A copper-catalyzed silylation of propargyl dichlorides was developed to access chloro-substituted allenylsilanes under mild reaction conditions. Moreover, enantioenriched chloro-substituted allenylsilanes can be synthesized in moderate to high yields and good enantioselectivities with this protocol.

  enantioselective synthesis of axially chiral chloroallenes from the propargylic dichlorides is reported, employing a catalytic amount of easily prepared SimplePhos ligand. Exclusive formation of the desired allenes was observed with good enantioselectivities (ee’s 62–96%). Further transformations to trisubstituted allenes or terminal alkynes with a propargylic quaternary carbon center keep a high level

  (Alk-1-ynyl)chlorocarbenes (3), generated from 1,1-dihaloalk-2-ynes and 3-substituted 3-bromo-1,1,1-trichloropropanes under the action of (BuOK)-O-t in THF at 20 degrees C, react with excess alkali metal alkoxide 4 to give 3-substituted 2-(alk-1-ynyl)oxiranes (6) in 26-78%; yields, most likely as a result of insertion of carbene 3 into the alpha C-H bond of alkoxides 4 and subsequent cyclization of the resulting 1-substituted 2-chloro-2-(alk-1-ynyl)etoxides. The yields of oxiranes 6 depend on the nature of the alkali metal used to prepare alkoxides 4 and on the method employed for the preparation of the latter.

  (丙-1-炔基)氯卡宾(3)由1,1-二卤代丙-2-炔与3-取代的3-溴-1,1,1-三氯丙烷，通过在四氢呋喃中用丁基氧化钾-O-t加热至20℃，与过量的碱金属烷基氧化物4反应，得到的产率为26-78%的3-取代的2-(丙-1-炔基)环氧乙烷(6)。产率的变化很可能是由于氯卡宾3插入到烷基氧化物4的α-C-H键，随后发生环化反应生成1-取代的2-氯-2-(丙-1-炔基)乙基氧化物所致。环氧乙烷6的产率依赖于制备烷基氧化物4时所用的碱金属种类以及制备方法。

  1,1-Dichloro-2-alkynes R1C=CCHCl2 (4a-g; R1 = Me, n-Pr, c-Pr, t-Bu, Ad, Nor, Ph) were synthesized with yield of 50-75% by chlorination with PCl5 of formylacetylenes (3a-g), prepared by oxidation of propargyl alcohols (1a-d) with CrO3.Py.HCl complex or acidolysis of propargyl acetals (2a-c) in the presence of catalytic quantities of pyridine; the corresponding alkynylchlorocarbenes, R1C=CCCl (5a-g) were generated from them with powdered KOH in a two-phase system or t-BuOK. The latter were trapped by olefins with formation of 1-chloro-1-alkynylcyclopropanes (6a-t) with yields of up to 90%.
