  通过[3,3]-趋向性重排，α，β-不饱和腈的Z-选择性α-芳基化

  摘要：

  Morita-Baylis-Hillman（MBH）反应和[3，3]-σ重排是有机合成的两个范例。我们将两种类型的反应合并在一起，以实现[3,3]-芳基亚砜与α，β-不饱和腈的重排。该反应是通过依次用亲电子活化剂（Tf 2 O）和碱处理两个偶合伙伴而实现的，提供了一种有效的方法，可通过直接的α-C-H芳基化制备具有Z-选择性的合成型多功能α-芳基α，β-不饱和腈未改性的α，β-不饱和腈 控制实验和DFT计算支持四个阶段的反应序列，包括Tf 2的组装O活化的芳基亚砜，具有α，β-不饱和腈，类似MBH的Lewis碱，[3,3]-重排和E1cB-消除。在这些阶段中，路易斯碱的加成是非对映选择性的，而E1cB-消除是顺式选择性的，这可能说明了反应的显着Z选择性。

  The invention comprises thio- or sulphonyl-substituted basic benzhydryl ethers and thioethers having sedative properties and represented by the formula wherein R is hydrogen, chlorine, bromine or iodine; R1 and R2 are alkylsulphonyl, alkylmercapto, phenyl- or substituted phenylmercapto, cycloalkyl- or substituted cycloalkylmercapto or hydrogen, and may be the same except when one of them is hydrogen; Z is oxygen or sulphur; and X is dialkylaminoalkyl, morpholinyl-substituted alkyl, piperidyl-substituted alkyl or N-alkyl-substituted C-piperidyl; and their acid or quaternary ammonium salts. They may be prepared by reacting a benzhydryl halide of the formula with the appropriate amino-alcohol or amino-thio-alcohol or their alkali metal salts; or by reacting the amino-halide with an appropriately substituted benzhydrol or benzhydryl-thio-alcohol or an alkali metal salt thereof. Solvents may be present. Examples disclose the preparation of hydrochlorides or citrates of the following compounds: benzhydryl 2-dimethylaminoethyl sulphides in which the benzhydryl group is substituted by p-methyl, p-ethyl, p-isopropyl-, o-, m- and p-butyl-, m- and p-hexyl-, p-cyclohexyl-, p-octyl- and p-phenyl-mercapto groups and by p,p1-bis(n-hexyl-, propyl- and butyl-mercapto) groups and by p-butyl sulphonyl: the p-butyl- and m-bromo-p1-butylmercapto and p,p1-bis(butylmercapto)-benzyhydryl 2-diethyl aminoethyl sulphides: m- and p-butyl-mercapto-benzhydryl 2-dimethylaminoethyl ethers: p-butylmercaptobenzhydryl-4-dimethyl-aminobutyl ether: p-butylmercaptobenzhydryl 2-(4-morpholinyl) ethyl ether and sulphide; p-butyl mercaptobenzhydryl 2-dimethylaminopropyl ether and sulphide: p-butylmercaptobenzhydryl 4-(1-methyl)-piperidyl sulphide: p-methylmercaptobenzhydryl 2-(1 - piperidyl) - ethyl ether: p-hexylmercaptobenzhydryl 2-(4-morpholinyl)-ethyl sulphide. The p-alkylmercaptobenzhydryl chlorides, used as starting materials, are prepared by reducing the p-alkyl mercaptobenzophenones (obtained from the p-alkylphenyl sulphides) with zinc and sodium hydroxide to the alcohol and then saturating with anhydrous HCl. The p-phenylmercapto-derivative is similarly prepared. The m-alkyl mercaptobenzhydryl chlorides are similarly prepared from the m-alkylmercaptobenzophenones which are obtained from the m-alkylmercaptobenzoyl chloride, benzene and anhydrous AlCl3 in CS2. The alkylmercaptobenzhydryl mercaptans are prepared by boiling the chloride with thiourea yielding the alkylmercaptobenzhydrylisothiouronium chloride which is then hydrolysed with aqueous sodium hydroxide. p-Butyl sulphonylbenzophenone is obtained by oxidizing p-butyl mercaptobenzophenone with hydrogen peroxide in glacial acetic acid. m - Bromo - p1 - butylmercaptobenzhydryl chloride is prepared by reacting butyl phenyl sulphide with m-bromobenzoyl chloride by the Friedel-Crafts synthesis to yield m-bromo-p1-butylmercaptobenzophenone, which is reduced by zinc and KOH to the alcohol which is then treated with HCl. p - Bromophenyl - n - butyl sulphide, prepared by brominating p-n-butyl phenyl sulphide, is converted to p-butyl mercaptobenzoic acid by carbonation of a Grignard derivative with CO2. The acid chloride, obtained by treatment with thionyl chloride, is reacted with butyl phenyl sulphide as above, yielding p,p1-bis (butylmercapto)-benzophenone. This is reduced to give p,p1-bis(butylmercapto)-benzhydrol, which is treated with HCl to give the chloride. Similar methods produce the p,p1-bis(propyl-and hexyl-mercapto)-derivatives.

  the fluoride substituent reacted more readily than the chloride and bromide. The reaction of hexafluorobenzene and a diaryl disulfide gave 1,4-diarylthio-2,3,5,6-tetrafluorobenzene, 1,2,4,5-tetraarylthio-3,6-difluorobenzene, and hexaarylthiobenzene in a stepwise manner; pentafluorobenzene gave 1-arylthio-2,3,5,6-tetrafluorobenzene; 1,2,3,4-tetrafluorobenzene gave 1,2-diarylthio-3,6-difluorobenzene;

  MCM-41-immobilized gold(I) chloride complex [MCM-41-2Ph2PAuCl] as the catalyst without using sacrificial oxidants. Vital to the success of this C-heteroatom coupling is the nucleophile-promoted activation of aryldiazonium salts, which can serve as an efficient oxidant for the conversion of Au(I) to Au(III) without the use of a photocatalyst or an assisting ligand. This new heterogenized gold(I) complex can
