Abstract
A [4+1]/[3+3] domino sequential annulation reaction of o-aminotrifluoroacetophenone derivatives and β'-acetoxy allenoates enabled by DMAP has been reported. A variety of CF3-containing tetrahydropyrano[3,2-b]indoles were obtained as a single diastereomer in high yields (≤98%) under mild conditions. The reaction can build one C-N bond, one C-C bond, and one C-O bond sequentially in a single step. The synthetic utility was demonstrated with gram-scale reactions and various transformations of the products.
