Synth�se d'alcools ac�tyl�niques par alkylation d'hydroxy-?-alkynes-1
摘要:
Synthesis of acetylenic alcohols by alkylation of ω‐hydroxy‐1‐alkynesIn liquid ammonia and with lithium amide, the alkylation of an ω‐hydroxyl‐alkyne proceeds with good yield with primary or secondary alcohols and with fair yield with tertiary alcohols. It is a very convenient way to prepare many substituted acetylenic alcohols.

Gold catalysis: Secondary 5‐hexyn‐1‐ol derivatives react with indoles and other heteroaromatic compounds under gold‐catalyzed conditions to give the corresponding ketone derivative (see scheme) through a cascade reaction involving an initial intramolecular hydroalkoxylation reaction of the triple bond followed by an intermolecular hydroarylation reaction and an unusual intramolecular Oppenauer‐type
