Synthetic intermediates derived from triterpenoids by the retro-michael reaction in the vapour phase

Dysotriflorins A–M, triterpenoids from Dysoxylum densiflorum

“…[23][24][25] It is to be noted that this is the first report on the isolation of 13,17-secodammarane triterpenoids. In addition, the isolation of ∆ 13 (17) -dammarane triterpenoids, such as 3-10, from the genus Dysoxylum have never been reported before.…”
