Total synthesis of racemic 8 15 diisocyano 11 20 amphilectene

, : Total synthesis of racemic 8 15 diisocyano 11 20 amphilectene. Journal of Organic Chemistry 54(7): 1483-1484

With 2-(methoxycarbonyl)-3-methylcyclohexanone and (E)-1-(tert-butyldimethylsiloxy)-6-iodo-3-(trimethylstannyl)-2-hexene as starting materials, the structurally novel, antimicrobial diterpenoid (.+-.)-8,15-diisocyano-11(20)-amphilectene (2) was synthesized in 20 steps.

An in vivo model to study the antimalaric effect of plant extracts is described. White mice (25-30 g body weight) are treated subcutaneously with 0.6 ml of the diluted extract starting seven days before P. berghei infection; treatment continues un...

The dose-response curves for their stimulation of germination and oxygen uptake were similar, indicating that these compounds may stimulate germinat...
