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, for example, cyclopropane carboxaldehyde is alkylated to form 1,1,1-trichloro-2-cyclopropyl-ethanol; which in turn is hydroxy protected to form 1,1,1-trichloro-2-cyclopropylethyltosylate; which in turn undergoes elimination 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.

权利人:UNIV RICE WILLIAM M
摘要:The present invention is directed to novel flame retardant monomers and polymers, wherein the flame retardant properties of the polymers are provided by functionality in pendant groups attached to a polymer backbone (as opposed to the polymer backbone itself possessing flame retardant properties. The present invention is also directed to methods of making such polymers and monomers, and articles of manufacture incorporating such monomers and polymers.
