Abstract
The diastereoselective nucleophilic addition of organic boronic ester to 3-hydroxy-2-substituted N-acyliminium ions 9 led to the formation of 2,5-cis-pyrrolidine 10, from which a convenient synthesis of (â)-7a-epi-1 was developed. In addition, an efficient asymmetric synthesis of (â)-hyacinthacine A1 1 was achieved through the reduction/ring-opening process.
