Up to date industrial application of methyllithium is limited because it is only soluble in diethyl ether, which amplifies various hazards in large-scale processes. However, most reactions require polar solvents like diethyl ether or TI-IF to disassemble parent organolithium oligomers. If classical bidentate donor solvents like TMEDA (TMEDA = N,N,N,N'tetramethyl- 1,2-ethanediamine) or DME (DME=1,2-dimethoxyethane) are added to methyllithium, tetrameric units are linked to form polymeric arrays that suffer from reduced reactivity and/or solubility. In this paper we present two different approaches to tune methyllithium aggregation. In [((MeLi)(4)(dem)(1.5)}(infinity)] (1; DEM - EtOCH2OEt, diethoxymethane) a polymeric architecture is maintained that forms microporous soluble aggregates as a result of the rigid bite of the methylene-bridged bidentate donor base DEM. Wide channels of 720 pm in diameter in the structure maintain full solubility as they are coated with lipophilic ethyl groups and filled with solvent. In compound 1 the long-range Li3CH3. . . Li interactions found in solid [{(MeLi)(4)}(infinity)] are maintained. A different approach was successful in the disassembly of the tetrameric architecture of [{(MeLi)(4)}(infinity)]. In the reaction of dilithium triazasulfite both the parent [(MeLi)(4)] tetramer and the [(Li-2[(NtBu)(3)S]}(2)] dimer disintegrate and recombine to give an MeLi monomer stabilized in the adduct complex [(thf)(3)Li3Me{(NtBu)(3)S}] (2). One side of the Lit triangle, often found in organolithium chemistry, is shielded by the tripodal triazasulfite, while the other face is mu (3)-capped by the methanide anion. This Li-3 structural motif is also present in organolithium tetramers and hexamers. All single-crystal structures have been confirmed through solid-state NMR experiments to be the same as in the bulk powder material."],["dc.identifier.doi","10.1002/1521-3765(20010401)7:7<1417::AID-CHEM1417>3.0.CO;2-Q"],["dc.identifier.isi","000167983700007"],["dc.identifier.pmid","11330894"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/26794"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-v C H Verlag Gmbh"],["dc.relation.issn","0947-6539"],["dc.title","[{(MeLi)(4)(dem)(1.5)}(infinity)] and [(thf)(3)Li3Me{(NtBu)(3)S}] - How to reduce aggregation of parent methyllithium"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

We have solved the x-ray structures of HP35 and its fastest folding mutant [K24 norleucine (nL)] to atomic resolution and compared their experimentally measured folding kinetics by using laser temperature jump. The structures, which are in different space groups, are almost identical to each other but differ significantly from previously solved NMR structures. Hence, the differences between the x-ray and NMR structures are probably not caused by lattice contacts or crystal/solution differences, but reflect the higher accuracy of the x-ray structures. The x-ray structures reveal important details of packing of the hydrophobic core and some additional features, such as cross-helical H bonds. Comparison of the x-ray structures indicates that the nL substitution produces only local perturbations. Consequently, the finding that the small stabilization by the mutation is completely reflected in an increased folding rate suggests that this region of the protein is as structured in the transition state as in the folded structure. It is therefore a target for engineering to increase the folding rate of the subdomain from approximate to 0.5 mu s(-1) for the nL mutant to the estimated theoretical speed limit of approximate to 3 mu s(-1)."],["dc.identifier.doi","10.1073/pnas.0502495102"],["dc.identifier.isi","000229417500023"],["dc.identifier.pmid","15894611"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/50837"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Natl Acad Sciences"],["dc.relation.issn","0027-8424"],["dc.title","High-resolution x-ray crystal structures of the villin headpiece subdomain, an ultrafast folding protein"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
