  • Patent number: 6613918
    Abstract: Ortho esters and ortho carbonates can be produced by alkylating esters and carbonates with, for example, the hexafluorophosphate salt of a trialkyl oxonium ion. The spiro species are useful intermediates in the synthesis of complex organic molecules. Synthetic pathways for the production of medically active compounds incorporates spiro ortho esters. Anti-first-pass effect materials are produced in high yield utilizing a synthetic strategy incorporating cyclic ortho ester intermediates.

  • Publication number: 20030105339
    Abstract: Psoralen compound compositions are synthesized which have substitutions on the 4, 4′, 5′, and 8 positions of the psoralen, which yet permit their binding to nucleic acid of pathogens. Reaction conditions that photoactivate these bound psoralens result in covalent crosslinking to nucleic acid, thereby inactivating the pathogen. Higher psoralen binding levels and lower mutagenicity results in safer, more efficient, and reliable inactivation of pathogens. In addition to the psoralen compositions, the invention contemplates inactivating methods using the new psoralens.

  • Patent number: 6420571
    Abstract: The present invention relates to methods for preparing 2,2-dimethyl-5-acyloxy -10-propyl-2H,8H-benzo[1,2-b:3,4-b′]dipyran-8-one (5) and 2,2-dimethyl-5-hydroxy-10 -propyl-2H,8H-benzo[1,2-b:3,4-b′]dipyran-8-one (6) and their use as intermediates for the synthesis of antiviral calanolide compounds. For example, Fries rearrangement on compound 5 or Friedel-Crafts reaction on 6, yields intermediate 2,2-dimethyl-5-hydroxy -6-propionyl-10-propyl-2H,8H-benzo[1,2-b:3,4-b′]dipyran-8-one (4), which, in turn, can be converted to (+)-calanolide A and (−)-calanolide B. The coupling of compound 6 with the appropriate chiral molecule under Mitsunobu or nucleophilic displacement leads to the asymmetric synthesis of antiviral calanolide compounds.

  • Patent number: 6384045
    Abstract: This invention provides cancer-active tricyclic and tetracyclic oxypyrones and a method of synthesizing these compounds. Preferred compounds have aryl groups at the 3-position of the oxypyrone ring. The tricyclic oxypyrone synthetic method is a simple condensation reaction of pyrones with cyclohexenecarboxaldehydes, providing high yields and using few steps. The tetracyclic oxypyrone synthetic method is a simple condensation reaction of carvones with pyrones.
