The Conformational Analysis of Saturated Heterocycles. Part 100. 1-Oxa-3-azacyclohexanes
Katritzky, Alan R.,Baker, Victor J.,Brito-Palma, Fernando M. S.
, p. 1739 - 1745 (1980)
Conformational equilibria and barriers to ring and nitrogen inversion are determined by 1H and 13C n.m.r. for 13 1-oxa-3-azacyclohexanes and correlated with recent work on the conformational analysis of saturated heterocycles.
Exploring the Conformation of Mixed Cis- Trans α,β-Oligopeptoids: A Joint Experimental and Computational Study
Dumonteil, Geoffrey,Bhattacharjee, Nicholus,Angelici, Gaetano,Roy, Olivier,Faure, Sophie,Jouffret, Laurent,Jolibois, Franck,Perrin, Lionel,Taillefumier, Claude

The synthesis and conformational preferences of a set of new synthetic foldamers that combine both the α,β-peptoid backbone and side chains that alternately promote cis- and trans-amide bond geometries have been achieved and addressed jointly by experiment and molecular modeling. Four sequence patterns were thus designed and referred to as cis-β-trans-α, cis-α-trans-β, trans-β-cis-α, and trans-α-cis-β. α- and βNtBu monomers were used to enforce cis-amide bond geometries and α- and βNPh monomers to promote trans-amides. NOESY and molecular modeling reveal that the trans-α-cis-β and cis-β-trans-α tetramers show a similar pattern of intramolecular weak interactions. The same holds for the cis-α-trans-β and trans-β-cis-α tetramers, but the interactions are different in nature than those identified in the trans-α-cis-β-based oligomers. Interestingly, the trans-α-cis-β peptoid architecture allows establishment of a larger amount of structure-stabilizing intramolecular interactions.

Design and evaluation of switchable-hydrophilicity solvents
Vanderveen, Jesse R.,Durelle, Jeremy,Jessop, Philip G.
, p. 1187 - 1197 (2014/03/21)
Switchable-hydrophilicity solvents (SHSs) are solvents that can switch reversibly between one form that is miscible with water to another that forms a biphasic mixture with water. For these SHSs, we use CO2 at 1 bar as a stimulus for triggering the transformation to the water-miscible form and removal of CO2 to achieve the reverse. We now report the identification of 13 new SHSs, including the first secondary amine SHSs, and a comparison of all known SHSs in terms of safety and environmental impacts. Amines which include another functional group, especially oxygen-containing groups, are less hazardous than alkylamines. Secondary amines can have improved switching speeds relative to tertiary amines. The variety of SHSs identified suggests that amine SHSs can be designed to have ideal properties for a given application.
Visible light-mediated synthesis of (Spiro)anellated furans

Visible light-mediated decarboxylation using N-acyloxyphthalimides as the source for carbon-centered radicals was applied for the synthesis of spirobutenolides. The utility of this approach is demonstrated with the formal synthesis of (S)-(+)-lycoperdic acid. Alternatively, 2,3-anellated furans can be obtained in a one-pot procedure via photocyclization following a regioselective semipinacol rearrangement.
Phenyl chloro(thionoformate): A new dealkylating agent of tertiary amines
Milan, David S.,Prager, Rolf H.
, p. 841 - 849 (2007/10/03)
Phenyl chloro(thionoformate) reacts rapidly with unhindered tertiary aliphatic amines at 20° to give a thiocarbamate and an alkyl chloride. Dialkylcyclohexylamines react surprisingly rapidly to form predominantly cyclohexene. The thiocarbamates are converted into the secondary amine salt by treatment with dimethyl sulfate, followed by hydrolysis with water. Rates of reaction and alkyl group cleavage selectivity in amines were found to be superior or comparable to those previously reported with chloroformates.
Monoalkylaminomethylation d'organometalliques a l'aide de N-alkyl N-trimethylsilyl alkoxymethylamines
Courtois, G.,Miginiac, L.
, p. 127 - 142 (2007/10/02)
The simple or functional N-alkyl-N-trimethylsilylalkoxymethylamines are very convenient new reagents for the route to unsymmetrical secondary functional amines from organometallic compounds (M=Al, Mg, Zn) prepared from α-unsaturated halides, functional terminal alkynes or α-bromoesters (or amides).
