Two cycloaddition strategies are described that lead to various chroman spiroketals from assorted exocyclic enol ethers. Unlike conventional thermodynamic ketalization strategies, the stereochemical outcome for this approach is determined b...
3-Acyloxy-1,4-enyne: a New Five-carbon Synthon for Rhodium-Catalyzed (5+2) Cycloadditions [0.03%]

200 years of research with carbon-rich molecules have shaped the development of modern chemistry. Research pertaining to the chemistry of boron-rich species has historically trailed behind its more distinguished neighbor (carbon) in the per...
Chemical composition-oriented receptor selectivity of L5, a naturally occurring atherogenic low-density lipoprotein [0.03%]
化学组成决定的L5受体选择性(L5是一种天然促动脉粥样硬化低密度脂蛋白)
