Indeed, reported examples of catalytic enantioselective synthesis of planar-chiral complexes have been rare, and this has been a developing area in this field. In this personal account, recent results from our research group on the catalytic asymmetric synthesis of various planar-chiral transition metal complexes are summarized. The asymmetric ring-closing metathesis reactions catalyzed by the well-defined molybdenum-alkylidene species are powerful methods to control the planar chirality in ferrocenes, ruthenocenes, (η6 -arene)chromium complexes, and (η5 -cyclopentadienyl)manganese(I) complexes. Application of the enantiomerically enriched complexes obtained by our methods is described as well. Representativeness of research populations impacts the ability to extrapolate findings. The Burn Model System (BMS) National Database is one of the largest prospective, longitudinal, multi-center research repositories collecting patient-reported outcomes after burn injury. To assess if the BMS Database is representative of the population that is eligible to participate. Data on adult burn survivors who were eligible for the BMS Database from 2015 to 2019 were analyzed. Not applicable. Burn survivors treated at BMS centers meeting eligibility criteria for the BMS Database. Eligibility for the database is based on burn size and receipt of autografting surgery. Not applicable. Race, ethnicity, gender, and age were compared between individuals who did and did not enroll. Regression analysis examined the correlation between demographic characteristics and study enrollment.
