Могу пока угостить абстрактом:

The ipso nitration of long-​chain alkyl ethers of p-​tert-​butylcalixarenes I [R = (CH2)​nMe, CH2CHEtBu; n = 4, 9, 11, 13, 15, 17] is possible with excellent yields of multi-​gram quantities by application of an improved procedure. Redn. of the nitro groups by catalytic hydrogenation leads conveniently to the corresponding p-​aminocalixarenes. These are interesting building blocks and starting materials for the prepn. of various new calixarene derivs. Some representative examples are given.
