We synthesized acetal aza-cage compounds directly via ozonolysis of 2,3-bis-endo-diol- and diacylnorbornenes in dichloromethane at −78 °C. Ozonolysis of the diols followed by addition of amines gave the aza-cage compounds in high yields. The reaction mechanism for the formation of this type of aza-cage compounds is proposed to proceed via the hydroperoxide intermediate. Ozonolysis of the diacetyl norbornene

Various multicyclic and bridged 1,4-diketones were subjected to the reductive conditions of the SmI2âHMPA system, often affording surprising results and reactivity upon fragmentation of the 2,3 CâC bond to provide the corresponding ring enlarged product.

A noval iodine-induced sequential cyclization reaction of norbornene derivatives leading to the formation of novel iodo-cage compounds

Teatment of the bis-endo-thioester and acyl group substituted norbornenes 1a–d and 9a–c with iodine in aqueous tetrahydrofuran at 25 °C gave the noval iodo-cage compounds 2a–d and 10a–c in 80–90% yields respectively, the first example of sequential cyclization of norbornene derivatives induced by an iodine electrophile.
The reaction mechanism for the conversion from oxa-cages into thia-cages was proposed. The diacetaltrioxa-cages 18-20 and 24-26 were also transformed into the thia-cages 21-23 and 27-29, respectively. Reaction of the trioxa-cages 34 and 35 with LR under the same reaction conditions gave the thia-cages 36 and 37 with the carbonyl group intact. Treatment of the pentaoxa[5]peristylane 40 with LR in chloroform
