Synthesis and cyclization reaction of cis,cis-1,3,5-triformyl-1,3,5-trimethy- cyclohexane

摘要

The hydrocarbon wurtzitane (fused boat cyclohexane) has been known since 1974. Nielsen and co-workers prepared the first wurtzitanes incorporating three het- eroatoms within the ring. They found the isomerization of triimines to triazawurtzitanes 1. However, they also reported that trioxawurtzitane 2 was not obtained from trialdehyde 3.
