-
Paragraph 0046-0048, (2018/06/16)
The invention provides a preparation method of a tiglic aldehyde derivative. The preparation method comprises the following step of carrying out catalytic oxidation on an isoamylene derivative represented as the following formula (I) in the presence of a catalyst to produce the tiglic aldehyde derivative represented as the following formula (II), wherein the catalyst is a non-metal oxide, and theR in the formula (I) or the formula (II) is selected from aliphatic hydrocarbyl, aryl, aralkyl, halogens, ester groups, acyloxy, acylamino or alkoxy. The preparation method of the tiglic aldehyde derivative provided by the invention has the characteristics of few reaction step, simple process, cheap and easily available raw materials and the like.

A practical synthesis of α,β-unsaturated aldehydes by a tandem-directed hydroformylation/β-elimination process of allylic o-DPPB esters is reported. The o-DPPB group served as an effective controller for regioselectivity of the hydroformylation towards th

Asymmetric hydroformylation of conjugated dienes such as vinylcyclohexene, (E)-phenyl-buta-1,3-diene and 4-methyl-penta-1,3-diene using BINAPHOS-RhI complexes as catalysts {(R,S)-BINAPHOS = [(R)-2-diphenylphosphino-1,1′-dinaphthalen-2′-yl] [(S)-1,1′-dinaphthalene-2,2′-diyl]-phosphite} gives optically active β,γ-unsaturated aldehydes in high regio- (81-91%) and enantio-selectivities (84-97% ee).
