are detected, consistent with allylation of the iminium intermediate being highly favored over allylation of the intermediate oxocarbenium ion. Acetals derived from aromatic aldehydes possessing a variety of functional groups and substitution patterns yield homoallylic amines with excellent levels of enantiomericenrichment. Experimental and computational data are consistent with an anchoring hydrogen-bond

Syntheses of new formylester- and cyanoester-substitutedbithiophenes, bifurans, and furanothiophenes in good yield are described. The key synthetic step uses Stille coupling of appropriately substituted bromo 5-ring heterocycles with stannyl-substituted 5-ring heterocycles.
