Cao, Zhi published the artcileTotal Synthesis of Two Pyrrole Spiroketal Alkaloids: Pollenopyrroside A and Capparisine B, Name: ((3aS,5aR,8aR,8bS)-2,2,7,7-Tetramethyltetrahydro-3aH-bis([1,3]dioxolo)[4,5-b:4′,5′-d]pyran-3a-yl)methanol, the publication is Synlett (2015), 26(7), 921-926, database is CAplus.
Pollenopyrroside A (I) and capparisine B (II), 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%, resp.
