new synthetic method for homopropargylic amines from alkylazides is presented. A salient feature of this reaction is the involvement of N-unsubstituted imines as the key intermediates, which are generated from alkylazides by Ru catalysis under photolytic conditions. Notably, this method avoids the use of a protective group strategy in the homopropargylic amine synthesis.

The pied piper‐idinol of Hamelin: The one‐pot synthesis of piperidin‐4‐ols by sequential gold‐catalyzed cyclization, chemoselective reduction, and spontaneous Ferrier rearrangement has a broad substrate scope and shows excellent diastereoselectivity in the ring‐formation step. This chemistry was employed in the six‐step enantioselective synthesis of (+)‐subcosine II.
Hamelin的pied piper-idinol:通过顺序金催化环化、化学选择性还原和自发费里叶重排一锅法合成哌啶-4-醇具有广泛的底物范围,并在成环步骤中显示出优异的非对映选择性。这种化学反应用于 (+)-亚余弦 II 的六步对映选择性合成。
