The multistep preparation of (11)C-levetiracetam ((11)C-LEV) was carried out by a one-pot radiosynthesis with 8.3 ± 1.6% (n = 8) radiochemical yield in 50 ± 5.0 min. Briefly, the propionaldehyde was converted to propan-1-imine in situ as labeling precursor by...

An efficient synthetic route was developed for the mild chloroacylation of chitosan with different chloroacyl chlorides. Full N-chloroacylation was obtained with this procedure without any O-acylation, and products having lower degrees of substitution can also be produced. Organo-soluble 6-O-triphenylmethylchitosan was...
