Podand ionophores with dialkoxy conformational locks
摘要:
Ionophores 2-4 which incorporate a novel +gauchel-gauche dialkoxy conformational locking mechanism were synthesized from D-mannitol. These new podands bound various chiral ammonium ions enantioselectively, but comparisons with related alkylated podands indicated that dialkyl and dialkoxy conformational locks are not completely interchangable.
