摘要
Diverse transformations of allenoates catalyzed by Lewis bases have emerged as a powerful platform for generating new chemical entities in organic synthesis. Herein, an N-heterocyclic carbene (NHC) catalyzed [3+3] cyclization of 2-(acetoxymethyl)buta-2,3-dienoates with 1 C,3O-bisnucleophiles has been developed. This approach provides a facile method to synthesize highly functionalized 4H-pyran derivatives with a broad substrate scope (31 examples, up to 83 % yield).
