N-Benzylhydroxylamine addition to beta-aryl enoates. Enantioselective synthesis of beta-aryl-beta-amino acid precursors.

Organic letters

Sibi MP, Liu M.
PMID: 11029219
Org Lett. 2000 Oct 19;2(21):3393-6. doi: 10.1021/ol006500e.

Chiral Lewis acid catalyzed N-benzylhydroxylamine addition to pyrrolidinone-derived enoates afforded beta-aryl-beta-amino acid derivatives in high enantiomeric purity with moderate to very good chemical efficiency.

Enantioselective conjugate addition of hydroxylamines to pyrazolidinone acrylamides.

Organic letters

Sibi MP, Liu M.
PMID: 11784172
Org Lett. 2001 Dec 27;3(26):4181-4. doi: 10.1021/ol016807t.

Chiral relay templates provide amplification of selectivity in conjugate addition reactions. Reversal of stereochemistry of the product isoxazolidinones has also been demonstrated by a simple change of the Lewis acid. [reaction: see text]

Forming supramolecular networks from nanoscale rods in binary, phase-separating mixtures.

Science (New York, N.Y.)

Peng G, Qiu F, Ginzburg VV, Jasnow D, Balazs AC.
PMID: 10846157
Science. 2000 Jun 09;288(5472):1802-4. doi: 10.1126/science.288.5472.1802.

Simulations show that when low-volume fractions of nanoscale rods are immersed in a binary, phase-separating blend, the rods self-assemble into needle-like, percolating networks. The interconnected network arises through the dynamic interplay of phase-separation between the fluids, through preferential adsorption...

Preparations of Trisubstituted Hydrazines and Pyrazolidines from N-(1-Benzotriazolylalkyl)hydrazines.

The Journal of organic chemistry

Katritzky AR, Qiu G, Yang B.
PMID: 11671935
J Org Chem. 1997 Nov 14;62(23):8210-8214. doi: 10.1021/jo9709110.

Reactions of N,N'-disubstituted hydrazines with benzotriazole and aldehydes give N-(alpha-benzotriazoylalkyl)-N,N'-disubstituted hydrazines which on treatment with organometallic reagents form N-alkyl-N,N'-disubstituted hydrazines in good yields. N-(Benzotriazolylalkyl)-N,N'-disubstituted hydrazines and electron-rich olefins, in the presence of zinc bromide catalyst, generate N,N'-disubstituted pyrazolidines in...

Confined supramolecular nanostructures of mesogen-bearing amphiphiles.

Chemical communications (Cambridge, England)

Zou B, Wang M, Qiu D, Zhang X, Chi L, Fuchs H.
PMID: 12123047
Chem Commun (Camb). 2002 May 07;(9):1008-9. doi: 10.1039/b201444k.

Stable surface nanostructures with different morphology have been successfully constructed by modifying the chemical structure of synthetic amphiphiles; by introducing mesogenic groups into bolaform amphiphiles, stable spaghetti-like or stripe-like nanostructures can be obtained; it is believed that such a...
