| titleOfInvention | A kind of preparation method of the acetaldehyde of 1,3 dithiane 2 |
| abstract | The acetaldehyde of 1,3 dithiane 2 is a kind of 1,3 important dithiane organic intermediate raw materials, and the compound has very high organic synthesis application value as multi-medicament structure and the precursor of bioactive molecule.The invention provides a kind of extremely succinct aldehyde-base 1 of no metal catalytic 2, the preparation method of 3 dithiane, at i.e. 0 DEG C, 1, after 3 dithiane and N chlorosuccinimides stir 1h in a solvent, appropriate vinyl ethers is then put into, and react 2h at room temperature, post-process direct vacuum fractionation and obtain the acetaldehyde compound of 1,3 dithiane 2.The raw material of the preparation method is cheap and easy to get, and reaction condition is gentle, and operation is simple, and the acetaldehyde raw material of 1,3 dithiane 2 is prepared with extensive available for enlarged experiment. |
