摘要:The present invention provides a highly efficient, versatile one-step process for asymmetric synthesis of either diastereomer of 2-substituted pyrrolidines from a single starting material with excellent yields and high diastereoselectivety. Also provided is a method for the asymmetric synthesis of both diastereomers of 2-substituted piperidines with good yields and excellent diastereoselectivety. Diasteroselectivity is controlled effectively by choice of reducing agent.

标 题:Molecular detection systems utilizing reiterative oligonucleotide synthesis
发明人：HANNA MICHELLE M
摘要:The present invention provides methods for detecting the presence of a target molecule by the use of nucleotide analogs containing moieties that enable detection. Such analogs may be incorporated into nucleic acids. In one embodiment, nucleotide analogs are used in a process generating multiple detectable oligonucleotides through reiterative enzymatic oligonucleotide synthesis events on a defined polynucleotide sequence. The methods generally comprise using a nucleoside, a mononucleotide, an oligonucleotide, or a polynucleotide, or analog thereof, to initiate synthesis of an oligonucleotide product that is substantially complementary to a target site on the defined polynucleotide sequence; optionally using nucleotides or nucleotide analogs as oligonucleotide chain elongators or chain terminators to terminate the polymerization reaction; and detecting multiple oligonucleotide products that have been synthesized by the polymerase.

标 题 :Vapor phase synthesis of cis-1, 4-Polyisoprene
发明人：CALDERON NISSIM; CASTNER KENNETH FLOYD; COLVIN HOWARD ALLEN; MUSE JR JOEL
权利人:GOODYEAR TIRE & RUBBER
摘要:By utilizing the vapor phase polymerization techniques of the present invention, numerous distinct and highly beneficial advantages are realized. For instance, cis-1,4-polyisoprene rubber and high cis-1,4-polybutadiene rubber having a consistent and controllable molecular weight can be easily and practically prepared without utilizing a solvent. The subject invention more specifically discloses a method for vapor phase polymerizing isoprene into cis-1,4-polyisoprene in a process comprising the steps of: (1) charging into a reaction zone said isoprene and a preformed catalyst system which is made by reacting an organoaluminum compound with titanium tetrachloride, preferably in the presence of at least one ether; wherein the isoprene is maintained in the vapor phase in said reaction zone by a suitable combination of temperature and pressure; (2) allowing said isoprene to polymerize into cis-1,4-polyisoprene at a temperature within the range of about 35 DEG C. to about 70 DEG C.; and (3) withdrawing said cis-1,4-polyisoprene from said reaction zone. It has been determined that gel formation can be reduced by conducting the polymerization of isoprene monomer in the presence of a diarylamine, such as para-styrenated diphenylamine.

摘要:The inventive subject matter relates to novel processes for making an epoxy alcohol from an aldehyde, comprising the steps of: (a) adding (i) an organozinc compound or (ii) divinylzinc compound and an diorganozinc compound to said aldehyde in the presence of a first catalyst to form an allylic alkoxide compound; and (b) epoxidizing said allylic alkoxide compound in the presence of an oxidant and a second catalyst.
