Evaluating Natural Course Performance in Parametric G-formula: Review of Current Practice and Illustration Based on the United Autoworkers-General Motors Cohort.

The parametric g-formula is a causal inference method that appropriately adjusts for time-varying confounding affected by prior exposure. Like all parametric methods, it assumes correct model specification, usually assessed by comparing the observed outcome with the simulated outcome under no intervention (natural course). However, it is unclear how to evaluate natural course performance and whether other variables should also be considered.

Cobalt-Catalyzed Regio-, Diastereo- and Enantioselective Intermolecular Hydrosilylation of 1,3-Dienes with Prochiral Silanes.

One of the most straightforward approaches to access chiral silanes is catalytic enantioselective hydrosilylation. Although significant advances have been achieved in enantioselective construction of either a carbon-stereogenic center or a silicon-stereogenic center through enantioselective hydrosilylation, simultaneous establishment of a carbon- and a silicon-stereogenic center in an acyclic molecule through a single intermolecular hydrosilylation remained undeveloped. Herein, an unprecedented cobalt-catalyzed regio-, diastereo- and enantioselective hydrosilylation of 1,3-dienes is presented, enabling construction of a carbon- and a silicon-stereogenic center in a single intermolecular transformation.
