Concise and Protective Group-Free Syntheses of (±)-Hamigeran B and (±)-4-Bromohamigeran B
摘要:
Concise and protective group free syntheses of (+/-)-hamigeran B and (+/-)-4-bromohamigeran B are reported. The key reactions include an enone migration and a Diels-Alder cyclization to provide the requisite tricyclic skeleton.
