  A Catalyst-Free Benzylic C–H Bond Olefination of Azaarenes for Direct Mannich-like Reactions

  摘要：

  A highly efficient synthesis of trans-alkenylazaarene under catalyst-free conditions was developed via the addition of methylazaarenes to N-sulfonyl aldimines and a subsequent C-N elimination in situ. A one-pot procedure for this addition-elimination was also developed. The reaction could tolerate a broad substrate scope and give the corresponding alkenylazaarenes in high yields.

  Under the influence of InCl3 as a Lewis acid catalyst, a methodology on the C(sp3)–H functionalization of alkylazaarenes has been demonstrated through the activation of benzylic C–H bonds towards their addition reaction with the appropriate electrophiles. This methodology was chiefly applied in the direct alkenylation of primary and secondary benzylic C–H bonds of alkylazaarenes with aldehydes. A variety

  azaheterocycle N-oxides with alkenes catalyzed by iodine under metal- and external oxidant-free reaction conditions has been developed. A variety of (E)-2-styrylazaheterocycles have been produced in moderate to excellent yields. The mechanistic exploration indicated that the N-oxide group played dual roles as both the directing group and an internal oxidant in this catalytic cycle.
