Sequential acylation-silylation of nitroalkanes leads to O-silylated α-acyloxyoximes in high yields. The first step of the reaction involves deprotonation of nitro compound with sodium hydride promoted by DBU or alcohol/15-crown-5 system followed by treat

The synthesis of 2-oxa and 2-aza analogs of pyrrolizidine-3,5-dione (Lukes-Sorm dilactam), which has amnesia reversal activity, is reported.Optically active (+)-2-oxa and (+)-2-aza analogs and racemic 2-aza analog and its 1-methoxycarbonyl derivatives were prepared from (-)-S-pyroglutamic acid and succinimide, respectively.
