摘要

A general, mild, and efficient 1, 2-migration/cycloisomerization methodology toward multisubstituted 3-thio-, seleno-, halo-, aryl-, and alkyl-furans and pyrroles, as well as fused heterocycles, valuable building blocks for synthetic chemistry, has been developed. Moreover, regiodivergent conditions have been identified for C-4 bromo-and thio-substituted allenones and alkynones for the assembly of regioisomeric 2-hetero substituted furans ...
