Hydantoin formation by cyclo-elimination: Reactivity difference between Merrifield- and Wang-derived resins
Park,Kurth
, p. 7409 - 7413 (2000)
cyclo-Elimination reactivity differences in I→II are reported. These reactivity differences dictate the selection of Wang resin for N1-substituted hydantoin formation and Merrifield resin for N1-unsubstituted hydantoin formation. (C) 2000 Elsevier Science Ltd.
