The Name is 2,5-Dimethoxybenzaldehyde. Through research, I have a further understanding and discovery of 93-02-7.
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 acid-catalyzed rearrangement as key steps. These cage polycycles were prepared starting with inexpensive synthons such as 2,5-dimethoxybenzaldehyde and endo-dicyclopentadiene. Propellanes 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 BF3 center dot MeOH. Several intricate cage structures were synthesized from rearrangement approach that are difficult to generate by conventional routes.
