Methods for preparing a variety of bryostatin compounds are provided. The subject methods provide for preparation of bryostatin 1 in multi-gram quantities in a low and unprecedented number of convergent synthetic steps from commercially available materials. The subject methods are scalable with low estimated material costs and can provide enough material to meet clinical needs. Also provided are a variety of bryostatin analog compounds, and prodrug forms thereof, which are synthetically accessible via the subject methods and pharmaceutical compositions including the same.提供用於製備多種苔蘚蟲素化合物的方法。該等標的方法提供由可商購的材料以少且無先例的數目的收斂式合成步驟製備以數公克量的苔蘚蟲素1。該等標的方法可在估計材料成本低的情況下規模化且可提供足夠的材料以滿足臨床需要。亦提供可經由該等標的方法合成獲得的多種苔蘚蟲素類似物化合物及其前藥形式以及包括其之醫藥組成物。
