Jjn. Veerman et al., A novel acid stable/base labile carbamate linker for N-acyliminium ion reactions on solid support, TETRAHEDR L, 40(33), 1999, pp. 6079-6082
The development of a novel carbamate linker optimized for solid phase N-acy
liminium ion chemistry is reported. Some 2- and 2,4-substituted pyrrolidine
s were synthesized via addition of several carbon nucleophiles to immobiliz
ed N-acyliminium ions. A beta-sulfonylethyl carbamate linker appeared espec
ially useful; readily synthesized, stable towards Lewis acids and easily cl
eavable. (C) 1999 Elsevier Science Ltd. All rights reserved.
