  Chiral C2-symmetric 2,5-disubstituted pyrrolidine derivatives as chiral catalyst ligands in the reaction of diethylzinc with arylaldehydes

  摘要：

  Two kinds of chiral C-2-symmetric 2,5-disubstituted pyrrolidine derivatives having a beta-aminoalcohol moiety were successfully synthesized and their catalytic abilities of asymmetric induction were examined in the reaction of diethylzinc with arylaldehydes. The production of sec-alcohols in high yields and high enantiomeric excesses having the R-configuration could be achieved when N-(2',2'-diphenyl-2'-hydroxyethyl)-(2R, 5R) -bis(methoxymethyl)pyrrolidine was used as a chiral ligand. On the other hand, when N-methyl-(2R, 5R)-bis(diarylhydroxymethyl)pyrrolidine was used as a catalyst, the enantiomeric excesses of the sec-alcohols went down and the inversion of the enantioselectivity was observed in the reaction of m-chloro-, p-chloro-, and m-fluorobenzaldehyde with diethylzinc.

  A new, conformationally rigid analogue of 2-amino­adipic acid, 8-[(benzyloxy)carbonyl]-3-methylene-8-azabicyclo[3.2.1]octane-1,5-dicarboxylic acid, is synthesized from dimethyl rac-2,5-dibromohexanedioate. The key steps involve alkylation-cyclization of 1-benzyl 2,5-dimethyl pyrrolidine-1,2,5-tricarboxylate with 3-chloro-2-(chloromethyl)prop-1-ene to yield the 8-azabicyclo[3.2.1]octane skeleton.

  trans-(2S.5S)-(1,1-Diphenylmethyl)pyrrolidine has been prepared from the corresponding diester in four steps and 54% overall yield. Key steps involve the nucleophilic addition of an organomagnesium reagent to a carbonyl compound promoted by cerium(III) chloride and the reductive removal of benzylic trimethylsilyloxyl groups with Me3SiCl-Nal-MeCN and water.
