Hydrocyanation of several phthalimidoalkynes proceeds with good regioselection yielding products which were easily converted into unsaturated and saturated β- and γ-amino acids.

When a hydrogen-oxygen flame was kept in contact with an aqueous formicacid solution of unsaturatedamines, carboxylation onto a double bond took place. This reaction revealed to be initiated by addition of a hydrogen atom to the double bond followed by coupling of the resulted substrate radical with a carboxyl radical.
Asymmetric Synthesis of Substituted Azetidine Type α- and β-Amino Acids

日期:——
A versatile asymmetricsynthesis of 3-substituted azetidine-2-carboxylic acids and 2-substituted azetidine-3-carboxylic acids via 1.3-amino alcohols with excellent stereoselectivities (de > 96%, ee > 96%) is reponed. The high asymmetric inductions were achieved employing the SAMP/RAMP-hydrazone methodology. A phenyl moiety was used as a synthetic equivalent of the carboxylic acid function. In addition
