摘要
The synthesis of 2,2-dimethyl-5-hydroxychromenc (1d) is described. The synthesis of the analogous 5,7-dihydroxy derivatives, using similar conditions, yields the adduct 9 derived via a Bucherer type reaction, X-ray analysis of 9 demonstrated that a pyrrolidine group was in the 7-postion, and that the 5-hydroxyl group was involved in a strong intramolecular hydrogen bond to the 4-keto oxygen atom.
