Preparation method of alpha-deuterated olefine aldehyde

The invention relates to a preparation method of alpha-deuterated olefine aldehyde, which comprises the following steps: by taking alpha, beta-olefine aldehyde as a raw material, carrying out a reversible Michael addition mechanism under the action of deuterium water, a nucleophilic reagent and an organic catalyst to obtain an alpha-deuterated olefine aldehyde compound. The method has high selectivity, and does not generate deuterated by-products at other positions. The alpha-deuterated olefine aldehyde compound prepared by the invention has great application value, can be further widely converted to prepare mono (poly) deuterated olefin and derivatives, olefine acid, conjugated olefine aldehyde, eneyne and other compounds, and has important significance in drug synthesis.

Dehydrogenative Synthesis of Linear α,β-Unsaturated Aldehydes with Oxygen at Room Temperature Enabled by tBuONO

Synthesis of linear α,β-unsaturated aldehydes via a room-temperature oxidative dehydrogenation has been realized by the cocatalysis of an organic nitrite and palladium with molecular oxygen as the sole clean oxidant. Linear α,β-unsaturated aldehydes could be efficiently prepared under aerobic catalytic conditions directly from the corresponding saturated linear aldehydes. Besides linear products, the aromatic analogy could also be smoothly achieved by the same standard method. The organic nitrite redox cocatalyst and alcohol solvent play a key role for realizing this method.
