FIB/SEM technology and high-throughput 3D reconstruction of dendritic spines and synapses in GFP-labeled adult-generated neurons.

Frontiers in neuroanatomy

Bosch C, Martínez A, Masachs N, Teixeira CM, Fernaud I, Ulloa F, Pérez-Martínez E, Lois C, Comella JX, DeFelipe J, Merchán-Pérez A, Soriano E.
PMID: 26052271
Front Neuroanat. 2015 May 21;9:60. doi: 10.3389/fnana.2015.00060. eCollection 2015.

The fine analysis of synaptic contacts is usually performed using transmission electron microscopy (TEM) and its combination with neuronal labeling techniques. However, the complex 3D architecture of neuronal samples calls for their reconstruction from serial sections. Here we show...

Dissociation of 70 S E. coli ribosomes induced by a ribosomal factor (DF). Electrophoretic studies of the ribosomal particles.

FEBS letters

J Talens, Kalousek F, Bosch L.
PMID: 11945527
FEBS Lett. 1970 Dec 23;12(1):4-8. doi: 10.1016/0014-5793(70)80580-4.

The dissociation of purified 70 S.E. coli ribosomes, induced by the dissociation factor DF, has been studied by submitting the reaction mixtures to electrophoresis on polyacrylamide gels. The electrophoretic analysis of the ribosome mixtures revealed a heterogeneity which escaped...

Generation and intermolecular reactions of 2-indolylacyl radicals.

Organic letters

Bennasar ML, Roca T, Griera R, Bosch J.
PMID: 11405689
Org Lett. 2001 May 31;3(11):1697-700. doi: 10.1021/ol0100576.

The generation of 2-indolylacyl radicals from the corresponding phenyl selenoesters, aldehydes, and alpha-keto carboxylic acids and the scope of their participation in intermolecular addition reactions to carbon-carbon double bonds have been studied. Whereas the phenyl selenoester method has provided...

One- and two-dimensional silver-coordination networks containing pi-sandwiched silver-silver interactions.

Inorganic chemistry

Bosch E, Barnes CL.
PMID: 11978124
Inorg Chem. 2002 May 06;41(9):2543-7. doi: 10.1021/ic010795q.

The self-assembly of coordination networks from reaction of 2,4,6-trimesityl-1,3,5-triazine and silver(I) trifluoroacetate is described. A one-dimensional linear polymer is formed from solutions deficient in silver while a two-dimensional, graphite-like sheet is formed from solutions containing 3 equiv of silver...

Palladium(0)-Catalyzed Heteroarylation of 2- and 3-Indolylzinc Derivatives. An Efficient General Method for the Preparation of (2-Pyridyl)indoles and Their Application to Indole Alkaloid Synthesis.

The Journal of organic chemistry

Amat M, Hadida S, Pshenichnyi G, Bosch J.
PMID: 11671699
J Org Chem. 1997 May 16;62(10):3158-3175. doi: 10.1021/jo962169u.

Palladium(0)-catalyzed coupling of (1-(benzenesulfonyl)-2-indolyl)zinc chloride (1) and (1-(tert-butyldimethylsilyl)-3-indolyl)zinc chloride (6) with diversely substituted (alkyl, methoxy, methoxycarbonyl, nitro, hydroxy) 2-halopyridines gives the corresponding 2- and 3-(2-pyridyl)indoles [4 and 7 (or 8), respectively] in excellent yields. A series of other 3-(heteroaryl)indoles...

Introduction of heteroatom-based substituents into 1,4-dihydropyridines by means of a halogen-mediated, oxidative protocol: diamination, sulfonylation, sulfinylation, bis-sulfanylation, and halo-phosphonylation processes.

Chemistry (Weinheim an der Bergstrasse, Germany)

Lavilla R, Kumar R, Coll O, Masdeu C, Spada A, Bosch J, Espinosa E, Molins E.
PMID: 10845634
Chemistry. 2000 May 15;6(10):1763-72. doi: 10.1002/(sici)1521-3765(20000515)6:10<1763::aid-chem1763>3.0.co;2-r.

The natural tendency of 1,4-dihydropyridines to undergo "biomimetic" oxidation to afford pyridinium salts can be switched off and, through the use of reagents that interact electrophilically with the enamine moiety present in the heterocyclic system, it is possible to...

Oxidative diphosphonylation of 1,4-dihydropyridines and pyridinium salts.

Organic letters

Lavilla R, Spada A, Bosch J.
PMID: 10841472
Org Lett. 2000 Jun 01;2(11):1533-5. doi: 10.1021/ol0057380.

An oxidative double phosphonylation of dihydropyridines 1 and pyridinium salts 2 is achieved through the use of dialkyl phosphites, DDQ, and triethylamine. Acceptable to good yields of 2, 6-diphosphonylated-1,2-dihydropyridines 3 are obtained in a one-pot reaction involving tandem nucleophilic...

1,2-Bis(2-pyridylethynyl)benzene, a novel trans-chelating bipyridyl ligand. structural characterization of the complexes with silver(I) triflate and palladium(II) chloride.
