Enantioselective Desymmetrization by Chiral Bifunctional H‐Bonding Organocatalysts

Chemistry – A European Journal, EarlyView.
Enantioselective desymmetrization has emerged as a highly efficient and conceptually elegant strategy for the construction of chiral molecules from readily available prochiral substrates. This review focuses on recent developments in organocatalytic desymmetrization reactions, with particular emphasis on approaches involving bifunctional activation ...

Vitamin D3 and women's health

Gynecology, 2019
Background. Vitamin D is an essential component that regulates calcium homeostasis and many other cellular functions. Hypovitaminosis D is associated with a risk of osteopenia, obesity, type 1 and type 2 diabetes, malignant neoplasms and immune disorders. Inadequate vitamin D intake during pregnancy increases a risk of pre-eclampsia, preterm birth, low
