Polyenolates of Unsaturated Carboxylic Acids in Synthesis. Synthesis of Unsaturated α-Amino Acids and β-Hydrazing Acids
摘要:
Regioselective reaction of lithium dieneand triene-diolates 1 and 2 with o-diphenylphosphinyl hydroxylamine affords unsaturated alpha-amino acids 3 and 4. Addition to DEAD leads selectively to gamma-hydrazino unsaturated acids 5 and 6.
