  • Chemical synthons and intermediates
    Patent number: 7501535
    Abstract: The invention provides novel six and seven-carbon termini-differentiated polypropionate stereotetrads and stereopentads useful in syntheses of natural products. The invention also provides a novel alkylative sulfenylation-desulfonylation process that efficiently transforms enantiopure epoxyvinyl sulfones to syn and anti dienylsulfides in two operations.
    Type: Grant
    Filed: September 15, 2003
    Date of Patent: March 10, 2009

  • Folic acid derivatives
    Patent number: 6291673
    Abstract: Novel folic acid derivatives and their use in preparation of &ggr;-esters of folic acid via a pteroyl azide intermediate are described. Folic acid &ggr;-esters are useful intermediates in the synthesis of folic acid conjugates capable of binding folate receptors in vitro and in vivo.
