Within the respiratory specialist community, there is growing recognition that classification of asthma based on severity of symptoms alone may not accurately reflect the clinical status of a patient. It follows, therefore, that treatment decisions b

A stereoselective entry to ryanoids is described that culminates in the synthesis of anhydroryanodol and thus the formal total synthesis of ryanodol. The pathway described features an annulation reaction conceived to address the uniquely complex and

The origin of the anomeric effect has been reexamined in a coordinated experimental and computational investigation. The results of these studies implicate a number of different, but correlated, interactions that in the aggregate are responsible for

Base-catalyzed equilibration of anancomeric cyanocyclohexanes demonstrates that replacement of cis-3,5-dimethyl holding groups with electron-withdrawing CF3 groups dramatically increases the proportion of the axial cyano isomer present at equilibrium

Anancomeric 5-phenyl-1,3-dioxanes provide a unique opportunity to study factors that control conformation. Whereas one might expect an axial phenyl group at C(5) of 1,3-dioxane to adopt a conformation similar to that in axial phenylcyclohexane, a ser

A complementary process to the Pauson–Khand annulation is described that is well suited to forging densely substituted/oxygenated cyclopentenone products (including fully substituted variants). The reaction is thought to proceed through a sequence

There is a potentially serious difference between diplomacy and intelligence. Creative tension between diplomacy and intelligence stems from the involvement of both with questions of strategy and statecraft. Indeed, the source of this conflict is oft
