Sports-related concussion in adolescents is a major public health issue; however, little is known about the underlying changes in functional brain connectivity. We evaluated connectivity of resting-state brain networks to determine whether alterations in specific networks distinguish adolescents with sports-related concussion from a group of healthy, active(More)
A new diversity-oriented approach to C7-cyclitols, which possess a broad spectrum of biological activities, is developed. The key polyoxygenated intermediates with different O-protecting groups were accessed by an intramolecular aldol-cyclization of a diketone derived from δ-d-gluconolactone. The versatile intermediates can be easily transformed into(More)
A stereoselective synthetic approach was utilized to synthesize enantiopure annuionones A (1b) and B (2b), two ionone-type norsesquiterpenoids that both bear a 6-oxabicyclo[3.2.1]octane framework and possess allelopathic activity. A stereoselective Diels-Alder reaction based on chiral trisubstituted dienophile 20 was employed to obtain the optically active(More)
