Preparation and ring-opening reactions of N-diphenylphosphinyl vinyl aziridines [PDF]

open access: yes, 2013
Predominantly (E)-N-diphenylphosphinyl vinyl aziridines are prepared by a reaction of N-diphenylphosphinyl imines with α-bromoallyllithium in the presence of freshly fused ZnCl2. These aziridines undergo a ring-opening reaction with a variety of carbon

Covalent drug discovery: Progress against key targets, emerging strategies and lessons learnt

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Covalent drug discovery is currently experiencing a boom in industrial and academic interest. To date, at least 75 covalent drugs have received regulatory approval, targeting both traditional target classes and more challenging proteins for which other approaches failed. In many cases, unique aspects of covalent targeting are essential for the

Synthesis of a Carbon‐Linked Acyldepsipeptide Derivative

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 15, 22 April 2026.
The synthesis of a methylene‐linked acyldepsipeptide (ADEP) is reported. Success relied upon an improve method to generate a versatile vinyl glycine methyl ester synthon and a rationally optimized Grubb’s metathesis. NMR and in silico studies revealed an unusual trans–trans proline orientation for this new unnatural ADEP analog, advancing the ...
