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.

权利人:UNIV KING ABDULLAH SCI & TECH
摘要:Embodiments of the present disclosure describe polymerization systems for the synthesis of polycarbonate polyols, methods of synthesizing polycarbonate polyols using the polymerization systems, methods of recovering initiators and/or activators for use or re-use in the synthesis of polycarbonate polyol, and the like. The polymerization systems can comprise an initiator including a mono- or multi-functional carboxylate or carbonate salt having an organic cation as a counter-ion; an optional co-initiator including a mono- or multi-functional protic compound selected from acids, alcohols, water, and combinations thereof; and an activator including a borane compound selected from alkyl boranes and aryl boranes; wherein the activator and one or more of the initiator and co-initiator associate to form an ate complex.

标 题 :Intermediates for preparing 1,6-dicarba-vasopressin compounds
发明人：CALLAHAN JAMES F; HUFFMAN WILLIAM F; NEWLANDER KENNETH A; YIM NELSON C F
权利人:SMITHKLINE BECKMAN CORP
摘要:New compounds which have potent V2-vasopressin antagonistic activity are prepared by a 1,6-cyclization using peptide bond formation. The structures of the compounds are characterized by the Pas1,6 or Tas1,6 cyclized unit. Also a chiral synthesis of the optically pure Pas intermediates is described.
