A chiral approach to (–)-pumiliotoxin C based on an aqueous intramolecular acylnitroso Diels–Alder reaction is described. Upon treatment of the (S)-1,3-diene hydroxamic acid 19, available from L-malic acid, with Pr4NIO4 under the aqueous conditions, the in situ generated acylnitroso compound 19 was subjected to intramolecular [4 + 2] cycloaddition to yield the trans-1,2-oxazino lactam 21 with significantly
