supporting information, p. 729 - 733 (2013/04/10)
A mild and convenient procedure for the synthesis of highly sensitive benzylic acetals from α,β-unsaturated aldehydes and the corresponding benzylic alcohols is reported. The new method provides a single-step access to these compounds for the first time.
Method for producing 3-methyl 2-butenal acetals
-
, (2008/06/13)
A process for preparing acetals of the formula I where a) the Rs are, independently of one another, a C1-C20-alkyl or C3-C20-alkenyl radical, or b) the two R radicals together form the members of an unsubstituted or C1-C10-alkyl-substituted 5- to 7-membered cyclic acetal, by reacting 3-methyl-2-butenal in the presence of sulfamic acid, of a N-(C1-C8-alkyl)sulfamic acid or of a N,N-di(C1-C8-alkyl)sulfamic acid as catalyst with: an alcohol of the formula R—OH (IIa), or an orthoester of the formula HC—(OR)3(III) or a mixture of an alcohol of the formula (IIa) and an orthoester of the formula (III), or an alcohol of the formula HO—(CH2)m—OH (IIb), where m is a number from 2 to 4, and (CH2)mgroup in the alcohol IIb may be substituted by a C1-C10-alkyl group.

For the systematic investigation of the odor of analogues of rose oxide (1),the seco-ethers 2-6, the cyclic nor-ethers 7-10,and the functionally varied compounds 11 and 12 were prepared.- For the typical spicy-herbaceous fragrance of 1 particularly the st
Action d'organometalliques sur les dialkylphenylorthoformiates. Preparation facile d'acetals
Barbot, Francis,Poncini, Laurence,Randrianoelina, Benjamin,Miginiac, Philippe
, p. 4016 - 4035 (2007/10/02)
The reaction of dialkylphenylorthoformiates with organometallic compounds proceeds with a good yield, at room temperature, giving the corresponding dialkylacetals ; it allows an easy preparation of acetals which are otherwise difficult to prepare.
