Publikováno v: Watts, O F B, Berreur, J, Collins, B S L & Clayden, J 2022, ' Biocatalytic Enantioselective Synthesis of Atropisomers ', Accounts of Chemical Research, vol. 55, no. 23, pp. 3362-3375 . https://doi.org/10.1021/acs.accounts.2c00572, https://doi.org/10.1021/acs.accounts.2c00572

ConspectusAtropisomeric compounds are found extensively as natural products, as ligands for asymmetric transition-metal catalysis, and increasingly as bioactive and pharmaceutically relevant targets. Their enantioselective synthesis is therefore an i

Autor: Roger W. Alder, Natalie Fey, Beatrice S. L. Collins, Aidan W. McFord, Craig P. Butts, Varinder K. Aggarwal, Valerio Fasano

Publikováno v: Aggarwal, V K, Fasano, V, McFord, A W, Butts, C P, Collins, B S L, Fey, N & Alder, R W 2020, ' How big is the pinacol boronic ester as a substituent? ', Angewandte Chemie-International Edition . https://doi.org/10.1002/anie.202007776

The synthetically versatile pinacol boronic ester group (Bpin) is generally thought of as a bulky moiety because of the two adjacent quaternary sp3 -hydribized carbon atoms in its diol backbone. However, recent diastereoselective reactions reported i

Enantiospecific Synthesis of ortho ‐Substituted 1,1‐Diarylalkanes by a 1,2‐Metalate Rearrangement/ anti ‐S N 2′ Elimination/Rearomatizing Allylic Suzuki–Miyaura Reaction Sequence

Autor: Raphael Bigler, Beatrice S. L. Collins, Varinder K. Aggarwal, Adam Noble, Belén Rubial, Stefan Aichhorn

Publikováno v: Angewandte Chemie International Edition. 58:1366-1370

The one-pot sequential coupling of benzylamines, boronic esters, and aryl iodides has been investigated. In the presence of an N-activator, the boronate complex formed from an ortho-lithiated benzylamine and a boronic ester undergoes stereospecific 1
