    摘要:
    诱导开环3→4需要强亲核试剂,因为由5-X-取代的5-氨基戊-2,4-二烯2经酸处理形成的吡喃鎓盐中间体3由于“芳族”稳定作用而几乎没有反应性。然而,这允许容易地从“推挽”烯炔1获得各种2-氨基吡啶鎓盐3。X = OAc,F,Cl,Br,I,OPh。

    Various 2-aminopyrylium salts 7 (X = Cl, Br, I) are available in a simple one-pot procedure by reacting 'push-pull' enynes 5 with equivalent amounts of HCl, HBr, or HI. On the other hand, reaction of NF or AcOH with 'push-pull' enynes 5 is considerably slower so that an excess of HF or AcOH I is needed for the reaction to 7 (X = F, AcO). The 2-aminopyrylium salts 7 are the key intermediates in the postulated rearrangement of 5-amino-5-halogeno-pentadienals 6 to 5-halogenopenta-2,3-dienamides 8 (Scheme 1, bottom), which is vinylogous to the well-known rearrangement of 3-amino-3-X-propenals 2 to 3-X-propenamides 3 (Scheme I, top).

    DOI:10.1002/(sici)1522-2675(19981216)81:12<2282::aid-hlca2282>3.0.co;2-m

    Contrary to the rearrangement of 3-amino-3-X-propenals, which easily gives 3-X-propenamides at Io cv temperature, the postulated rearrangement (Scheme I) of the vinylogous 5-amino-5-X-pentadienals 2 normally stops at the level of (2H-pyran-2-ylidene)ammonium salts 4. The main reason is that salts of type 4 are highly delocalized low-energy. charged species which makes addition 4-5 of weak nucleophiles difficult. In this paper, the first examples of the so-called 'aminopentadienal' rearrangement art: reported. Ring-opening 4 - 6 is facilitated by nucleophilic counter ions like X = PhO (see Scheme 4) or by adding an excess of 'nucleophilic auxiliaries' such as Et3N or EtOH (see Scheme). In a quite interesting sequence of steps, 5-phenoxy-5-(pyrrol-1-yl)penta-2,4-dienal (2g; X=PhO) is easily transformed into 5H-pyrrolo[1,2-a]azepin-5-one (9) (Scheme 5).
