ABSTRACT

The precise placement of C-substituents on bicyclic and spirocyclic N-heterocycles is readily achieved by the combination of aldehydes and new SnAP reagents. The substituted SnAP reagents are readily prepared from simple starting materials and couple with a variety of aromatic and heteroaromatic aldehydes at room temperature under operationally simple conditions to deliver substituted morpholine and piperazine products.
