Photochemisch induzierte Reaktionen von 3‐Amino‐2H‐azirinen

Abstract: 1. Einleitung. -Die Chemie der 2H-Azirine ist eingehend untersucht und in zahlreichen Arbeiten beschrieben worden (obersichtsartikel [ 1-41; fur neuere Arbeiten siehe [5-121 und dort zit. Lit.). Die leichte Zuganglichkeit dieses gespannten Stickstoffdreiringes (vgl. z. B. [ 13-16]), sowie die Moglichkeit, unter geeigneten Reaktionsbedingungen jede der drei Ringbindungen selektiv zu spalten, machen 2 H-Azirine zu wertvollen Synthesebausteinen fur N-haltige Verbindungen. Theoretische Untersuchungen [ 171 sowie R… Show more

“…the synthesis of 2H-azirin-3-amines 1 [35], used by Strässler for the preparation of 1b (n = 1) [12], is limited to N-alkyl-N-phenyl derivatives, we decided to prepare N- (9), with the aim of following the protocol of the aminoazirine synthesis published by Rens and Ghosez [36] and modified by Dietliker [37]. Thus, tetrahydro-2H-thiopyran-4-carboxylic acid chloride (6) [12] was reacted with L-proline methyl ester (7) to give N-[(tetrahydro-2H-thiopyran-4-yl)carbonyl]-L-proline methyl ester (8) in 85% yield, which was converted to 9 by thionation with Lawesson reagent in 67% yield (Scheme 2).…”
