    摘要:
    Ketoester 1 is cyclized to give pyran-3,5-dione 2 in 78% yield using a parallel addition of ketoester 1 and base NaOBu in refluxing THE Compared to the previously reported procedures, these optimized conditions have significantly increased the yield of this transformation and the quality of pyran 2 and prove to be suitable for large-scale preparation. An application of 2 to the synthesis of ABT-598, a potassium channel opener, is demonstrated.
