Enantioselective Total Synthesis of (—)-Acetylaranotin, a Dihydrooxepine Epidithiodiketopiperazine [PDF]
, 2012 The first total synthesis of the dihydrooxepine-containing epidithiodiketopiperazine (ETP) (−)-acetylaranotin (1) is reported. The key steps of the synthesis include an enantioselective azomethine ylide (1,3)-dipolar cycloaddition reaction to set the ...

Logic‐Gated Release of a Dual Payload from a β‐Lactam Mechanophore with a Rotaxane Actuator
Angewandte Chemie, EarlyView.A rotaxane device operates as a logic AND gate to release a single or dual cargo payload upon application of force in the absence or the presence of water, respectively. This concept was demonstrated with the release of a ketene and varied drugs, paving the way for precision release applications.

Asian Journal of Organic Chemistry, EarlyView.High‐valent Rh(IV) and Rh(V) species have been invoked to rationalize enhanced catalytic reactivity. This review examines evidence for both, emphasizing reactions proceeding through the Rh(III)/Rh(IV)/Rh(II) cycle. While Rh(V) intermediates are computationally supported, experimental evidence is limited; Rh(IV) species are supported by both theory and ...

Animal Models and Experimental Medicine, EarlyView.Grafts used to construct lung cancer animal models come from various sources, primarily cell lines, patient‐derived tumor tissues, and circulating tumor cells. Based on the sources of grafts and research objectives, lung cancer animal models can be categorized into several types: chemical‐induced models, orthotopic transplantation models, heterotopic ...
