  • Patent number: 6452000
    Abstract: The present invention concerns an improved process for the preparation of asymmetric cyclic ureas as well as intermediates in the preparation of asymmetric cyclic ureas. In the process, a diamine of formula (I-a) is selectively monoacylated to give an asymmetric monoacylated diamine which can be converted into asymmetric intermediates. The asymmetric intermediates can be further alkylated, cyclized, and/or modified to give compounds which are useful as HIV protease inhibitors for the treatment of HIV infection. The invention allows for scalable preparation of a wide variety of asymmetrical cyclic ureas.

  • Patent number: 6049019
    Abstract: The present invention relates generally to novel methods for the synthesis of cyclopropylacetylene which is an essential reagent in the asymmetric synthesis of (S)-6-chloro-4-cyclopropylethynyl-4-trifluoromethyl-1,4-dihydro-2H-3,1-ben zoxazin-2-one; a useful human immunodeficiency virus (HIV) reverse transcriptase inhibitor. In the process, cyclopropane carboxaldehyde is condensed with malonic acid to form 3-cyclopropylacrylic acid; 3-cyclopropylacrylic acid is halogenated to form (E,Z)-1-halo-2-cyclopropylethylene; and (E,Z)-1-halo-2-cyclopropylethylene is dehydrohalogenated to form cyclopropyl acetylene. This improvement provides for high conversion of inexpensive, readily available starting materials into cyclopropylacetylene, high overall yields and can be conducted on an industrial scale.
