摘要：

Pollenopyrroside A and capparisine B, two diastereoisomers of pyrrole spiroketal alkaloids isolated from Brassica campestris pollen and Capparis spinosa, were synthesized by an improved microwave-assisted bishydroxymethylation of pyrrole and acid-catalyzed spirocyclization as key steps with total yields of 2.7 and 8.8%, respectively.
