    摘要： This application discloses a novel process for the preparation of phosphonate esters useful as intermediates in the preparation of himbacine analogs, themselves useful as thrombin receptor antagonists. The chemistry taught herein can be exemplified by the following scheme: wherein R9 is selected from alkyl, aryl heteroaryl and arylalkyl groups having 1 to 10 carbon atoms, and R11 is selected independently for each occurrence from alkyl, aryl heteroaryl and arylalkyl groups having 1 to 10 carbon atoms and hydrogen, X2 is Cl, Br, or I; X3 is selected from Cl and Br; and PdLn is a supported palladium metal catalyst or a soluble heterogeneous palladium catalyst. The L-derivatizing reagent is a moiety which converts the alcohol functional group of compound 137D to any leaving group which can be displaced by a triorgano-phosphite phosphonating agent.

    摘要： An icemaking compartment is provided in the refrigerator compartment of a bottom mount refrigerator. An icemaker is within the icemaking compartment. A cold air duct supplies cold air from the freezer compartment to the icemaker. The cold air duct is formed in the rear wall of the refrigerator. A fan controls the flow of air through the cold air duct. A return air duct is provided to direct a portion of the air from the icemaker back to the freezer compartment. An air vent in the icemaker directs another portion of air into the refrigerator compartment.

    摘要： A refrigerator includes a freezer compartment and a fresh food compartment which includes an ice chamber. The ice chamber includes an ice maker which includes a first heat exchanger for producing ice. The ice chamber further includes an ice container, a second heat exchanger, an air moving apparatus, and an enclosed loop passageway. The ice container is for storing ice produced by the ice maker and includes an exterior surface. The second heat exchanger is for controlling temperature at the ice container. The passageway forms an air flow path such that air travels in thermal contact with the second heat exchanger. The air moving apparatus is positioned to move air through the passageway.
