Convenient methods for the synthesis of new types of mono-and diphosphorus-substituted proline derivatives containing P–C–N fragments were developed based on special pre-prepared proline-containing synthons. The corresponding organophosphorus acids including a proline fragment were also synthesized.

AbstractA new type of amine fragmentation under electron impact is elucidated for proline, sarcosine and aspartic acid derivatives and aminomethylphosphines of the general formula R2NCH2X. Ordinary α‐cleavage affording the \documentclassarticle}\pagestyleempty}\begindocument}$ \rm R}_2 \mathop \rm N}\limits^\rm + } \rm = CH}_\rm 2} $\enddocument} ion is suppressed by elimination of a neutral HX particle and [M ‐ HX]+ ion formation, or M‐HX neutral particle ejection and generation of an [HX]+ ion from [M]+˙. Such fragmentation is ensured by the presence of an α‐heteroatom (N, O, P, S) in one substituent (X) and a CO2R type delocalizing group in the α‐position of the other substituent (R2N).
