- Synthetic method for cis-1,4-cyclohexanediol
-
The invention discloses a synthetic method for cis-1,4-cyclohexanediol, belonging to the field of organic chemical synthesis. According to the method, 4-(alkylacyloxy)cyclohexanone is used as a raw material and is only subjected to reduction and hydrolysis so as to conveniently synthesize cis-1,4-cyclohexanediol. The method can guarantee high selectivity of the reactions, and is high in the yieldof cis-1,4-cyclohexanediol and suitable for large-scale production.

- Lanthanum(III) isopropoxide catalyzed chemoselective transesterification of dimethyl carbonate and methyl carbamates
-
A practical transesterification of less reactive dimethyl carbonate and much less reactive methyl carbamates with primary (1°), secondary (2°), and tertiary (3°) alcohols was established with the use of a lanthanum(III) complex, which was prepared in situ from lanthanum (III) isopropoxide (3 mol %) and 2-(2-methoxyethoxy)ethanol (6 mol %). In particular, corresponding carbonates and carbamates obtained were of synthetic utility from the viewpoint of the selective protection and/or deprotection of 1°-, 2°-, and 3°-alcohols.
