N-acyl/sulfonyl iminium ions with (n-Bu)3SnCN. Employing readily removable N-acyl/sulfonyl groups as protectinggroups rather than N-aryl ones enables a wide range of applications in natural product synthesis. The synthetic utility of the method was illustrated using a short and efficient formaltotalsynthesis of (±)-calycotomine in three steps.
Affinity of 2-(tetrahydroisoquinolin-2-ylmethyl)- and 2-(isoindolin-2-ylmethyl)imidazolines for .alpha.-adrenoceptors. Differential affinity of imidazolines for the [3H]idazoxan-labeled .alpha.2-adrenoceptor vs the [3H]yohimbine-labeled site

A series of 2-(tetrahydroisoquinolin-2-ylmethyl)- and 2-(isoindolin-2-ylmethyl)imidazolines were prepared and tested for alpha 1- and alpha 2-adrenoceptor affinity with radioligand binding. Several compounds, 5-fluoro-(5h), 5-chloro-(5j), 5,8-dimethoxy- (5r), and 5,8-dimethoxy- (5r),1-methyl- (5s) 2-(tetrahydroisoquinolin-2- ylmethyl)imidazoline, were found to be selective alpha 2-adrenoceptor ligands
