01 - 053Pd-Catalyzed Selective Addition of Heteroaromatic C–H Bonds to C–C Triple Bonds under Mild Conditions. — A novel palladium-catalyzedaddition reaction of heteroaromatic compounds to alkynoates is developed. Inmost cases, exclusively cis-heteroarylalkenes like (III) are obtained. However,with small substituents in the alkynoates, mainly diaddition products, e.g.(VII), are afforded. — (LU, WENJUN; JIA, CHENGGUO; KITAMURA,TSUGIO; FUJIWARA, YUZO; Org.
