摘要:
The first asymmetric total synthesis of the natural pyrrole lactone longanlactone has been achieved. The key reactions, a Barbier propargylation and a Paal-Knorr pyrrole synthesis, have provided easy access to the target natural product from L-aspartic acid in six steps and 31% overall yield. The C-4 epimer of the natural product and propionyllonganlactone have also been prepared by this strategy.
