Reaction of N‐Protected Succinimides with α‐Lithiated Acetic Acid Derivatives

Abstract

The complex cis-Pt(ll)( 1 -naphthylan~ine)~CI~ was synthesized by reaction of K2PtC14 with I-naphthylamine in water/dimethylformamide (DMF) and obtained analytically pure by nm light into the LF band did not lead to substitution of I-naphthylamine (d<

Intramolecular Reversible Addition Reactions to the C=O Group

“…Both opposing effects may explain the increased stability of the ring isomer for N-methylamides only. A great number oflevulinic [33,189,199,218,220,230,231,234,235], other 3-acylpropionic (R 1 = alkyl) [199,220,236,237], 3-aroylpropionic [33,197,199,202,203], and methylsubstituted acylpropionic [141,200,221,231,237,238] ami des were synthesized and their structures strictl,Y proven by means of spectroscopic methods. But one rarely succeeded in obtaining both individual isomers.…”

“…3-Acylpropionic amides, bearing methyl groups in the chain, predominantly, also possess a cyclic structure [141,200,221,231,237,238].…”
