Second Generation Catalytic Enantioselective Nucleophilic Desymmetrization at Phosphorus (V): Improved Generality, Efficiency and Modularity

Michele Formica, Branislav Ferko, T. R. Marsh, Timothy A. Davidson et autres

Abstract A broadly improved second generation catalytic two‐phase strategy for the enantioselective synthesis of stereogenic at phosphorus (V) compounds is described. This protocol, consisting of a bifunctional iminophosphorane (BIMP) catalyzed nucleophilic desymmetrization of prochiral, bench stable P(V) precursors and subsequent enantiospecific substitution …

A second generation catalytic two-phase strategy for the enantioselective synthesis of chiral at P(V) compounds is described. This protocol, consisting of a bifunctional iminophosphorane (BIMP) catalyzed nucleophilic desymmetrization of prochiral, bench stable P(V) precursors and subsequent enantiospecific substitution allows for divergent access …

Cobalt‐Catalyzed Multi‐Substituted Alkene Synthesis from 1,3‐Dithiolanes and Grignard Reagents

Timothy A. Davidson, Samiha Anam, Heyao Shi, Darren J. Dixon

Abstract The cobalt‐catalyzed reaction between 1,3‐dithiolanes and Grignard reagents, for the efficient synthesis of multi‐substituted alkene products, is described. The method was applicable to a variety of benzylic dithiolane substrates, affording di‐, tri‐, and tetra‐substituted 1,1‐diaryl alkene products in good to excellent …

Branching out: redox strategies towards the synthesis of acyclic α-tertiary ethers

Benjamin D. A. Shennan, Diana Berheci, Jessica L. Crompton, Timothy A. Davidson et autres

redox approaches has facilitated the synthesis of highly sterically-encumbered ethers and accordingly these strategies have been widely applied in α-tertiary ether synthesis. This review summarises and appraises the state-of-the-art in the application of redox strategies enabling acyclic α-tertiary ether synthesis.

The Effect of Acute Respiratory Distress Syndrome on Long-term Survival

Timothy A. Davidson, Gordon D. Rubenfeld, Ellen Caldwell, Leonard D. Hudson et autres

Despite a great deal of information about the risk factors, prognostic variables, and hospital mortality in the acute respiratory distress syndrome (ARDS), very little is known about the long-term outcomes of patients with this syndrome. We conducted a prospective, matched, parallel cohort …

Reduced Quality of Life in Survivors of Acute Respiratory Distress Syndrome Compared With Critically Ill Control Patients

Timothy A. Davidson, Ellen Caldwell, J. Randall Curtis, Leonard D. Hudson et autres

CONTEXT: Health-related quality of life (HRQL) is reduced in patients who survive acute respiratory distress (ARDS), but whether this decline in HRQL is caused by ARDS or other aspects of the patient's illness or injury is unknown. OBJECTIVE: To determine if there …
