Structurally, momilactones belong to 9β-H pimarane diterpenoids, one of rice’s significant allelochemicals with anti-weeds and antibacterial activity. Rare studies have been reported with the synthesis challenges of the unique 9β-H pimarane skeleton. Hence, synthetic strategies of momilactones and related 9β-H pimarane skeleton are reviewed from 1984 to 2021.
