Paragraph 0032-0047, (2021/11/26)
The method comprises the following steps: carrying out selective hydrogenation reaction on limonene under the action of a hydrogenation catalyst; and after the reaction is finished, the citronellal is obtained. In the synthesis process MOFs, the adopted hydrogenation catalyst is introduced into a metal site with catalytic activity, so MOFs materials have a specific catalytic capacity, the catalytic effect of the catalyst is improved, the conversion rate and selectivity are improved, and the obtained product has better fragrance. The invention also discloses a hydrogenation catalyst for the preparation method.

For the dehydroxylation of aldoximes with 4-nitro-1-((trifluoromethyl)sulfonyl)-imidazole (NTSI), slight modifications of reaction conditions resulted in significantly different reaction paths to provide either nitriles or isonitriles. The challenging conversion of aldoximes into isonitriles was achieved under mild conditions.

A cyanide-free platform technology for the synthesis of chiral nitriles by biocatalytic enantioselective dehydration of a wide range of aldoximes is reported. The nitriles were obtained with high enantiomeric excess of >90 % ee (and up to 99 % ee) in many cases, and a “privileged substrate structure” with respect to high enantioselectivity was identified. Furthermore, a surprising phenomenon was observed for the enantiospecificity that is usually not observed in enzyme catalysis. Depending on whether the E or Z isomer of the racemic aldoxime substrate was employed, one or the other enantiomer of the corresponding nitrile was formed preferentially with the same enzyme.
