THE USE OF β-LACTAMS IN THE SYNTHESIS OF SPERMINE AND SPERMIDINE ALKALOIDS. TOTAL SYNTHESIS OF HOMALINE
Wasserman, Harry H.,Berger, Gregory D.
, p. 2459 - 2464 (1983)
The optically active plant product homaline (6) has been synthesized in a convergent sequence starting with β-phenyl-β-alanine and putrescine (14).The key transformation in this sequence is the ring expansion by transamidation of a functionalized chiral β-lactam precursor.
