Preparation of aldehydes from esters
TLDR
In this article, organics are reduced to ALDEHYDES by using SODIUM ALUMINUM HYDRIDES of the formulae NAA1HX (or 1)4-X at a low temperature, in an ETHER OR AROMATIC HYDROCARBON.Abstract:
ORGANIC ESTERS ARE REDUCED TO ALDEHYDES BY USING SODIUM ALUMINUM HYDRIDES OF THE FORMULA NAA1HX(OR1)4-X AT A LOW TEMPERATURE, PREFERABLY IN AN ETHER OR AROMATIC HYDROCARBON, R1 IS ETHER LOWER ALKOXY LOWER ALKYL, LOWER DIALKYLAMINO LOWER ALKYL, TETRAHYDROFURFURYL OR PYRANYLMETHYL. THE REACTION IS CARRIED OUT BELOW 0* C. PREFERABLY -40 TO -70* C.read more

Process for producing alicyclic aldehydes
TL;DR: In this paper, a starting aromatic aldehyde is converted into an aromatic acetal for protecting the formyl group, which is then hydrogenated to convert the aromatic ring into an alicyclic acetal and then hydrolyzed to cleave the acetal protecting group.

Preparation of aliphatic aldehydes from esters
TL;DR: Aliphatic aldehydes are prepared from carboxylic acid esters of primary alcohols by contacting the latter with a wide variety of oxidized elements selected from V, Sb, Mo, and W as well as oxidized element from groups I, III-B, IV, VII-A, and VIII of the periodic system of elements as discussed by the authors.

NEW PROCESS FOR OBTAINING alpha-AMINO NITRILES AND THEIR APPLICATIONS TO ORGANIC SYNTHESIS
Gerard Moinet,Imbert Thierry +1 more
TL;DR: In this article, a process for the synthesis of alpha-amino nitriles is described, which comprises subjecting an RCN nitrile to the action of a metal reducing agent to form a metal imine, and treating the latter with a cyaniding agent in order to obtain a compound of formula (I).
