    摘要: There is provided batch methods of making cyclopropene complex involving mixture comprising (i) one or more molecular encapsulating agent and (ii) solvent, wherein the ratio of the amount of said (i) to the amount of said (ii) is higher than the solubility of said molecular encapsulating agent in said solvent. There is also provided continuous methods of making cyclopropene complex in which the ratio of the rate of addition of molecular encapsulating agent to the rate of addition of solvent is higher than the solubility of said molecular encapsulating agent in said solvent.

    摘要: The present invention relates to a method to prepare cyclopropenes by combining an allyl compound of the formula:
    wherein:

    X is a leaving group; and
    R is hydrogen or a substituted or unsubstituted alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkylalkyl, phenyl or naphthyl group wherein the substituents are independently halogen, alkoxy, or substituted or unsubstituted phenoxy;
    with a non-nucleophilic strong base in an inert solvent in the presence of a catalytic amount of a non-nucleophilic, weaker base.

    摘要: 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-benzoxazin-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.
