摘要：
The heteroannulation catalyzed by silver salts of alkynols 1, 2 or alkynoic acids 3 is considerably enhanced by the presence of a propargylic C-O bond, This method allows for a rapid access to highly functionalized heterocycles, such as alpha-methylene oxolanes 4 or oxanes 5 and as gamma-methylene pentanolactones 6.
