Manoalide methyl analogue (MMA, 12), which is a simple analogue of the reactive portion of 1, reacted similarly. The γ-(n-butyl-amino)butenolide 6b reacted with hydroxylamine to form the oxime 8 with concomitant release of n-butylamine. When the luffariellolide-PLA 2 and manoalide-PLA 2 adducts were treated with hydroxylamine, the PLA 2 activity was substantially recovered, but the activity was not recovered
