Abstract: |
This report confirms that sodium tertiary‐pentoxide is a very effective base for the nucleophilic addition of acetylenes to aldehydes and ketones in 1,4‐dioxane at room temperature. These mild and operationally simple procedures have been working well with a variety of aromatic and heteroaromatic aldehydes and also equally working well with aliphatic, aromatic and heteroaromatic ketones. A very clean product of secondary and tertiary propargylic alcohols were obtained from 70–94% yield. This process has been explored in bulk scale synthesis on selected molecules and also adapted the column free purification for most of the substrates. |
