Polyether-bridged cyclophanes incorporating bisphenol A units as neutral receptors for quats: Synthesis, molecular structure and binding properties

Two novel neutral polyoxyethylene bridged cyclophanes (2a and 2b) incorporating bisphenol A units were synthesized and characterized by means of x-ray crystal structure determination. The binding properties of 2a and 2b toward tetramethylammonium, N-methylpyridinium, and acetylcholine cations were evaluated by means of 1H NMR spectroscopy. Consistent with indications provided by the molecular structure, the cavity in the basket-like cyclophanes is large enough to accommodate the given guest cations conveniently. Circumstantial evidence was obtained that 1,1,2,2-tetrachloroethane is too large to enter the cavity of the smaller cyclophane 2a, but can be included in the cavity of the larger cyclophane 2b.

An ether-linked tetrafunctional acylating reagent and its cross-linking reactions with hemoglobin

A new type of tetrafunctional reagent for cross-linking proteins has been prepared and used to modify human hemoglobin A. DPEE (1,2-bis{2-[3,5-bis(3,5-dibromosalicyloxycarbonyl) phenoxy]ethoxy}ethane)) has two separate pairs of reacting sites connected by
