Notes: Synthesis of 15-Hydroxy[9]metacyclophane3-(1-Nitro-2-oxocyclododecyl)propanal (1) was converted to 15-hydroxy[9]metacyclophane (3) on two different routes. In the first case the internal aldol reaction product of 1 was treated with K2CO3/THF to give 3 in 29 % yield with regard to cyclododecanone. Alternatively, the aldehyde 1 reacted with a primary amine to form e.g. 4 which gave 3 in the presence of CH3I/K2CO3 in 48 % yield.
