New polystyrene-based resins containing benzyl and aryl vinyl sulfone groups are described. The vinyl sulfone group reacts efficiently with 2°amines, via conjugate addition, and the resin-bound 3°amines products can be quaternised through alkylation. Subsequent deamination to give 3°amines and the regenerated vinyl sulfone occurs in moderate to good yield. Both systems can be recycled and show moderate stability to acids and high stability to nucleophiles including Grignard reagents.

4-[(α,α-Diaryl)-hydroxymethyl]-1-piperidinylalkylcyclic carbamate derivatives having the formula: STR1 wherein; R is hydrogen, loweralkyl, cycloalkyl, phenyl and substituted phenyl; Ar and Ar1 are phenyl, substituted phenyl or pyridinyl; alk is a straight or branched hydrocarbon chain; R1 is loweralkyl substituted for hydrogen on a ring carbon. The compounds are useful antihistamines and in controlling allergic response.
