Sw/onary. The base-catalyzed condensation of p-t-butylphenol and formaldehyde, which yields a cyclic octamer (I, n-8) as the major product, has been shown to also yield a cyclic tetramer (I, n=4) and a bishomoo~a cyclic tetramer (II). The base-catalyzed reaction of p-substituted phenols and formalde
Ortho-tert-butylcalixarenes 3, 4 and 5 with exo-hydroxy groups were synthesised by tin tetrachloride-promoted condensation of 2,2"-dihydroxy-3,3"-di-tert-butyldiphenylmethane 6 with formaldehyde. While tH NMR analysis of compounds 3, 4 and 5 revealed a considerable annular flexibility in CDCI3 solut
