  Functionalized chloroenamines in aminocyclopropane synthesis - XIV. Aminoannulated cyclopropanes - rigid building blocks for oligoamines

  摘要：

  Sterically pure meander oligoamines 5 possessing bicyclo[3.1.0]hexyl moieties as rigid building blocks were synthesized from monoketal 9 via di(chloroenamine) 14, bicyclic diketones 16 and subsequent reductive amination of 16. Use of the same reactions and change of the sequence of the steps led to hexamine 6a, a diastereomer of 5a. Hexamine 7a, a third diastereomer of 5a, was obtained with definite stereochemistry by a multistep approach starting from monoketal 9, too. X-Ray analysis of hexamine 5a, determination of basicity and studies of conformation and of molecular flexibility gave an insight in structural properties of the new type of meander oligoamines 5.
