The design and synthesis of highly decorated cage [4.3.2] propellanes and D 3 -trishomocubanes have been reported via ring-closing metathesis (RCM), [4 + 2] cycloaddition and acidcatalyzed rearrangement as key steps. These cage polycycles were prepared starting with inexpensive synthons such as 2,5dimethoxybenzaldehyde and endo-dicyclopentadiene. Propel-lanes containing fused spiro[4.4]nonane ring system was realized by RCM protocol. Interestingly, the dimethoxy cage propellane derivative was observed instead of the rearranged product with Lewis acid such as BF 3 ⋅MeOH. Several intricate cage structures were synthesized from rearrangement approach that are difficult to generate by conventional routes.[a] Prof.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
