  Joint cycloalumination of ethylene and other unsaturated compounds with EtAlCl2 in the presence of Cp2ZrCl2. Synthesis of aluminacarbocycles

  摘要：

  A procedure has been developed for the selective synthesis of five-membered aluminum-containing heterocycles, 2,3-dialkyl-1-ethylaluminacyclopent-2-enes, 3-alkyl-1-ethylaluminacyclopentanes, 2-alkylidene-1-ethylaluminacyclopentanes, and 3-alkyl-1-ethyl-2-methylidenealuminacyclopentanes, via joint cycloalumination of ethylene and other unsaturated compounds (acetylenes, olefins, and allenes) with EtAlCl2 in the presence of Cp2ZrCl2 as catalyst.

  The chemo- and enantioselectivity of the reaction of alkenes with AlEt3 catalyzed by bis(1-neomenthyl-indenyl)zirconium dichloride has been studied. The reaction with linear alkenes in a chlorinated solvent (CH2Cl2) gives mainly carbometallation products in 70-80% yield and with enantiomeric purity of 47-70%ee with an (S)-configuration. In the case of vinylcycloalkanes and styrene, the reaction provides roughly equal amounts of carbometallation products and substituted alumolanes with enantioselectivities of 39-69%ee and 40-57%ee, respectively.(R)-MTPA and (R)-2-phenylselenopropionic acid [(R)-PSPA] were used as the derivatization reagents for enantiomeric excess estimation and the absolute configuration assignment of beta-chiral primary alcohols and 2-substituted 1,4-butanediols resulting from oxidation and hydrolysis of the organoaluminum products. It was shown that the specific rotation changes sign in the series of enantiomerically enriched 2-ethyl-1-alkanols when going from beta-ethyl-substituted octanol to nonanol. The conformational analysis of the MTPA and PSPA esters of 2-ethyl-1-alkanols was performed and a dependence of their conformational composition on the type of substituent at the beta-stereogenic center was established. Calculation of the Se-77 NMR chemical shifts of the possible conformers of the PSPA esters demonstrated that the conformation of the selenium moiety has the most pronounced effect on the delta(Se) value. The high efficiency of PSPA application for the enantiomeric purity estimation and the absolute configuration assignment of 2-ethyl-1-alkanols is shown. (C) 2014 Elsevier Ltd. All rights reserved.
