  A Novel [3+2] Cycloaddition Approach to Nitrogen Heterocycles via Phosphine-Catalyzed Reactions of 2,3-Butadienoates or 2-Butynoates and Dimethyl Acetylenedicarboxylate with Imines:  A Convenient Synthesis of Pentabromopseudilin

  摘要：

  The reactivity of a new three carbon synthon, generated in situ from the reaction of 2,3-butadienoates or 2-butynoates with an appropriate phosphine as the catalyst, toward the electron deficient imines is described. Triphenylphosphine-catalyzed reaction of-methyl a,3-butadienoate with N-sulfonylimines gave the single [3+2] cycloadduct in excellent yield; tributylphosphine-catalyzed reaction of methyl 2,3-butadienoate or 2-butynoate with N-tosylimines afforded the corresponding [3+2] cycloadduct as the major product along with a small amount of the three components adduct. Aliphatic N-tosylimines gave moderate yield for this reaction. In addition, a new phosphine-catalyzed cyclization reaction of dimethyl acetylenedicarboxylate with N-tosylimines is also described. A:reaction mechanism is proposed. Further elaborations of the cycloaddition products and the synthesis of pentabromopseudilin using this method are exemplified.

  顺序氮杂-Baylis-Hillman /环闭合复分解/芳构化作为合成取代吡咯的新途径

  摘要：

  已经开发出一种新的途径来制备各种2-取代的3-甲氧基羰基吡咯。通过3-组分氮杂-Baylis-Hillman反应获得了多种SES保护的α-亚甲基β-氨基酯。可以用于该反应的芳基醛引起多样性。在温和条件下用烯丙基溴进行N-烷基化可提供相应的二烯。这些取代的二烯通过在室温下或在用格鲁布斯（Grubbs）II型催化剂进行微波活化下的闭环复分解反应而环化，得到SES保护的吡咯啉中间体。最终的吡咯是通过碱促进的脱氢脱亚磺酰化/芳香化获得的。探索了每个反应的范围。

  2-substituted-3-methoxycarbonyl pyrroles has been developed. Diverse SES protected α-methylene β-aminoesters were obtained by a 3-component aza-Baylis−Hillman reaction. Diversity arose from the aryl aldehydes which can be used in this reaction. N-Alkylation with allyl bromide under mild conditions provided the corresponding dienes. These substituted dienes were cyclized by ring closing metathesis at room

  aza-Baylis−Hillman/alkylation/RCM route. While deprotection of Ts-protected pyrrolines gave only pyrroles, deprotection of the same SES-protected compounds gave either pyrroles or free amine pyrrolines depending on the deprotection conditions. The SES-protected pyrrolines were hydrogenated to yield pyrrolidines with an excellent diastereoselectivity. Free amine pyrrolidines were obtained by HF-mediated
