Unsymmetrically substituted 1,3-butadiynes and 1,3,5-hexatriynes are synthesized in four steps from commercially available aldehydes or carboxylic acids. The key step in this process involves a Fritsch-Buttenberg-Wiechell rearrangement, in which an alkylidene carbenoid intermediate subsequently rearranges to the desired polyyne. This rearrangement proceeds under mild conditions, and it is tolerant

Rhodium vinylidene intermediates are characteristic for the title reaction (see scheme; coe=cyclooctene, cy=cyclohexyl). This reaction proceeds by the nucleophilic addition of the nitrogen atom of the imine to the rhodium vinylidene complex to give a zwitterionic intermediate, which undergoes intramolecular cyclization to afford the corresponding pyrrole.

This work reports gold‐catalyzed iminations of terminal propargyl alcohols with anthranils or isoxazoles to yield E‐configured α‐amino‐2‐en‐1‐ones and ‐1‐als with complete chemoselectivity. These catalytic iminations occur exclusively with C(1)‐nucleophilic additions on terminal alkynes, in contrast to a typical C(2)‐route. For 3,3‐dialkylprop‐1‐yn‐3‐ols, a methyl substituent is superior to long alkyl

suitable to perform hydration of TMS-substituted propargyl acetates, even though it requires prolonged reaction time for completion. Stereointegrity of the propargylic acetate is preserved during the hydration. The robustness of the system is successfully demonstrated through gram scale preparation of the product in nearly quantitative yield. The common α-acyloxy methylketone is transformed to 1,2-diol
