  Transition metal-catalyzed radical cyclizations: a low-temperature process for the cyclization of N-protected N-allyltrichloroacetamides to trichlorinated .gamma.-lactams and application to the stereoselective preparation of .beta.,.gamma.-disubstituted .gamma.-lactams

  摘要：

  Cyclizations of N-substituted N-allyltrichloroacetamides, where the substituent is an alkyl, Cbz, Boc, Ts, or Ms group, are catalyzed by a 1:1 mixture of CuCl and bipyridine to give the corresponding beta,gamma-trichlorinated gamma-lactams in high yields. The reactions proceed at temperatures from -78-degrees-C to room temperature. Cyclizations of N-allyltrichloroacetamides of acyclic secondary allylic amines are achieved with good selectivity; the cis/trans ratios of the gamma-lactams formed were dependent on the substituents on the nitrogen atom. The stereochemical outcome is compared with that of free-radical cyclization.

• Synthesis of α-Chlorolactams by Cyanoborohydride-Mediated Radical Cyclization of Trichloroacetamides

  日期：2018.6.7

  A cyanoborohydride‐promoted radical cyclization methodology has been developed to access α‐chlorolactams in a simple and efficient way using NaBH3CN and trichloroacetamides easily available from allylic and homoallylic secondary amines. This methodology allowed the synthesis of a library of α‐chlorolactams (mono‐ and bicyclic), which were tested for herbicidal activity, trans‐3‐chloro‐4‐methyl‐1‐(

  We report herein an unprecedented protocol for radical carbotrifluoromethylation of unactivated alkenes. With Cu(OTf)2 as the catalyst, the reaction of unactivated alkenes, TMSCF3 and activated alkyl chlorides at room temperature provides the corresponding carbotrifluoromethylation products in satisfactory yields. Directed by trifluoromethylation of alkyl radicals, the method exhibits an excellent

  我们在此报告了未活化烯烃的自由基碳三氟甲基化的空前协议。用Cu（OTf）2作为催化剂，未活化的烯烃，TMCSF 3和活化的烷基氯在室温下的反应以令人满意的产率提供了相应的碳三氟甲基化产物。通过烷基的三氟甲基化指导，该方法显示出优异的区域选择性，这与CF 3自由基添加所驱动的区域选择性相反。

  日期：——

  A new procedure for the synthesis of γ- and δ-lactams based on a Cp2TiCl-catalysed cyclisation of trichloroacetamides under mild reaction conditions is reported. Theoretical studies supported the observed regioselectivity in the cyclisations and the mechanism involved in the dehalogenation process.
