The reaction of a silyl enol ether bearing a nitrogen atom with a hemiacetal vinylog in the presence of a catalytic amount of boron trifluoride etherate led to the corresponding ketoaldehyde. The cyclisation of the ketoaldehyde into azaspiroenone and nitrogen deprotection was performed in basic medium. The N-benzylation of this enone gave the known key intermediate of total synthesis of (±)-perhydrohistrionicotoxin. Georg Thieme Verlag Stuttgart.

When N-methoxycarbonyl and N-benzoxycarbonyl derivatives of methyl esters of aziridine-2-carboxylic acid, L-proline, L-thioproline, and pipecolic acid interact with NaBH4 in tert-butanol/methanol, the products of reduction of the C-methoxycarbonyl group o
