专利号:US-6417380-B1 优先权日:1987-12-31 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.

专利号:US-8710220-B2 优先权日:2009-12-10 标题 :Synthesis of 8-amino boron dipyrromethenes having blue fluorescence 发明人:PE A CABRERA EDUARDO; AZAEL CÉSAR FERNANDO; FLORES JUAN ORLANDO 权利人:PE A CABRERA EDUARDO; AZAEL CÉSAR FERNANDO; FLORES JUAN ORLANDO; UNIV GUANAJUATO 摘要:A family of six 8-amino boron dipyrromethenes having Formulas 1, 2, 3, 4, 6, and 7 has been prepared. The presence of the amine group alters the emission properties of the boron dipyrromethene, such that these compounds are characterized by unexpected blue fluorescence, providing for potential use as lasers. The compound having formula 1 has very high quantum yield. The 8-amino boron dipyrromethenes are prepared in a straightforward, high yield synthesis by substituting an amine group for the thiomethyl group at the 8 position in 8-thiomethyl boron dipyrromethene. The compounds having Formulas 6 and 7 may be used to incorporate peptides and proteins, thus providing biomolecules marked with fluorescent fragments.
