标 题 :Synthesis of 1,2-dioxetanes and intermediates therefor
发明人：BRONSTEIN IRENA Y; EDWARDS BROOKS
摘要:Compounds having the formula: n wherein T is a polycycloalkylidene group (e.g., adamant-2-ylidene); R is a C 1-20 alkyl, aralkyl or cycloalkyl group; and Y is a fluorescent chromophore (e.g., n m-phenylene), produced by reacting a compound having the formula: n with an R-ylating agent (e.g., R 2 SO 4 ) in the presence of an alkali metal alkoxide in a polar aprotic solvent. Also, compounds having the formula: n are produced by reacting a compound having the formula: n with n wherein X is an electronegative leaving group (e.g., a halogen anion such as chloride ion) in the presence of a Lewis base (e.g., a trialkyl-amine) dissolved in an aprotic organic solvent (e.g., benzene or toluene). Also, compounds having the formula n are produced by reacting a compound of the formula n with a tetra-O-acylated-O-hexopyranoside halide, then hydrolyzing off the protective acyl groups. The aforementioned compounds and procedures are useful in the synthesis of enzyme-cleavable 1,2-dioxetane ring systems that can serve as members of a binding pair employed, for example, in chemiluminescent immunoassays, DNA probe assays, and direct assays for an enzyme.

标题:Synthesis of energetic polyester thermoplastic homopolymers and energetic thermoplastic elastomers formed therefrom
发明人：AMPLEMAN GUY; BROCHU SYLVIE
权利人:DEPT OF NAT DEFENCE
摘要:Polymerization of α-bromomethyl-α-methyl-β-propiolactone (BMMPL) or α-chloromethyl-α-methyl-β-propiolactone (CMMPL) yielded thermoplastic homopolymers that upon azidation led to a novel energetic thermoplastic polyester: poly(α-azidomethyl-α-methyl-β-propiolactone) (PAMMPL). An energetic copolyether-ester thermoplastic elastomer was prepared by using glycidyl azide polymer, a dihydroxyl terminated energetic polymer, as a macroinitiator for the polymerization of BMMPL or CMMPL. The azidation of the resulting copolyether-ester yielded an energetic thermoplastic elastomer that melted at between 80° C. and 85° C. Polymerization of α-dibromomethyl-β-propiolactone (DBMPL) resulted in a polymer which upon azidation yielded a new energetic polymer that can be used as a binder or into an energetic thermoplastic elastomer synthesis.
