A Deiters, D Hopp. Asymmetric synthesis of cis-1,2-dialkenyl-substituted cyclopentanes via (-)-sparteine-mediated lithiation and cycloalkylation of a 9-chloro-2,7-nonadienyl carbamate. The Journal of organic chemistry. vol 66. issue 8. 2001-12-04. PMID:11304210. the described cycloalkylation reaction starts with a (-)-sparteine-mediated asymmetric deprotonation of the 2,7-alkadienyl carbamate 7e and leads to the enantioenriched (80% ee) and diastereomerically pure (dr = 99:1) cis-1,2-divinyl-cyclopentane 8, by a subsequent cyclization and elimination of lithium chloride. 2001-12-04 2023-08-12 Not clear
E Legrand, I Filliol, C Sola, N Rastog. Use of spoligotyping to study the evolution of the direct repeat locus by IS6110 transposition in Mycobacterium tuberculosis. Journal of clinical microbiology. vol 39. issue 4. 2001-08-23. PMID:11283094. the sequencing of the central dr region corroborated our previous findings and showed that the absence of spacer 31 among the type 50 isolates was due to the asymmetric insertion of an extra copy of is6110 between spacers 31 and 32, leading to an unequal split of the dra-drb target into two portions, of 6 and 30 bp, respectively. 2001-08-23 2023-08-12 Not clear
W H Boesten, J P Seerden, B de Lange, H J Dielemans, H L Elsenberg, B Kaptein, H M Moody, R M Kellogg, Q B Broxterma. Asymmetric strecker synthesis of alpha-amino acids via a crystallization-induced asymmetric transformation using (R)-phenylglycine amide as chiral auxiliary. Organic letters. vol 3. issue 8. 2001-07-12. PMID:11348174. the strecker reaction is accompanied by an in situ crystallization-induced asymmetric transformation, whereby one diastereomer selectively precipitates and can be isolated in 76-93% yield and dr > 99/1. 2001-07-12 2023-08-12 Not clear
