权利人:WANG GUIJUN; MANGUNURU HARI P R; OLD DOMINION UNIV RES FOUND
摘要:Described herein are the one-pot synthesis and characterization of a library of low molecular weight peptoid compounds that are able to form gels at room temperature. The compounds are synthesized from biologically-based starting materials, are biocompatible, and are resistant to degradation by proteases and peptidases. The compounds and gels synthesized therefrom can be used in such applications as tissue engineering, drug delivery, separation of biomolecules, and stimulus-responsive advanced materials

标题:Cobalt catalyzed steroid synthesis
发明人：FUNK RAYMOND L; VOLLHARDT K PETER C
权利人:U S OF AMERICA HEW SECRETARY
摘要:Steroid compounds obtained by co-oligomerization of a side chain functionalized 1,5-hexadiyne with bis(trimethylsilyl)acetylene catalyzed by cyclopentadiene cobalt dicarbonyl, CpCO(CO) 2 , via intermediate benzocyclobutene formation followed by intramolecular cycloaddition to the sterospecific formation of the steroid nucleus. This constitutes a short steroid synthesis, five steps from commercially available acyclic precursor 1,5-hexadiyne and three steps from 2-methyl-cyclopent-2-enone.

摘要:This invention relates to the synthesis of certain novel Baylis-Hillman adducts of artremisinin derived aldehyde 2-[10′β-deoxoartemisininyl]-ethanal. The capabilities of introduction of three functional groups into a molecule in one step using Baylis-Hillman reaction encouraged us to synthesize some highly functionalized derivatives of artemisinin. These highly functionalized artemisinin derivatives embodied in this document are found to be active against various cancer cell-lines.

摘要:A method is provided for making an enantiomerically pure compound of the formula: in which R and R′ represent C1?C10 alkyl, C2?C10 alkenyl or C3?C10 cycloalkyl and the wedges signify (S)- or (R)-stereochemistry, the substituents in compound (II) being trans. Conjugate addition is carried out between an organometallic nucleophile that provides a group R as defined above and (R)-4-acetoxycyclopent-2-en-1-one, (S)-4-acetoxycyclopent-2-en-1-one or a similar compound in which acetoxy is replaced by another leaving group to give, e.g. in the case of the acetoxy compound, a trans 3,4-disubstituted addition product of formula III or IV; The acetyl group is eliminated from the addition product to give an (R)- or (S)-4-alkyl or 4-alkenyl cyclopent-2-en-1-one the compound of formula is then to be hydrogenated to give a cyclopentanone of formula (I) or conjugate addition of a second organometallic nucleophile that provides a group R′ as defined above to the compound of the above formula may be carried out to give a trans 3,4-disubstituted addition product of formula (II). One of the above compounds may be converted e.g. via an intermediate (XV)-(XVIII) (in which the substituents R and R′ and the wedges have the meanings indicated above) to a gabapentin analogue of one of the formulae shown below: in which the substituents R and R′ and the wedges also have the meanings indicated above.

摘要:Preparation of thermally and/or photochemically crosslinkable oligomeric precursors and the use of those oligomeric precursors in preparing crosslinked electroactive polymers are described. The oligomers, polymers, and synthetic methods find utility in the manufacture of opto-electronic devices such as light emitting diodes, photoconductors, photovoltaic cells, and the like, wherein synthesis of electroactive films and polymeric multilayers is required.
