Synthesis of (.+‐.)‐Phloeodictine A1. [PDF]
ChemInform, 2003 The antitumor antibiotic phloeodictine A1 (2) has been synthesized by a convergent seven-step route in 8% overall yield. The key step was the Eguchi aza-Wittig reaction of 6 to give 13 followed by a retro Diels-Alder reaction to liberate 5. Addition of 11-dodecenylmagnesium bromide to 5 to give 4b, alkylation with 18b, and deprotection completed the ...

Il Nuovo Cimento A, 1969 The coupling of the A1 to a three-pion system is studied through the analysis of some simple two-body amplitudes where the A1 appears as an either external or internal particle. The A1→3π decay amplitudes to a pion and aP-wave orS-wave ππ system are related in the Veneziano model.
