Synthesis of ?-formyl-2,5-dialkoxytetrahydrofurans and their reaction with 3-amino-1,2,4-triazole

Applied Hydroformylation

“…Claver and co-workers have studied effects that govern the regioselectivity of the hydroformylation of acyclic allyl ethers using Rh catalysts with monodentate phosphines and phosphites. , As expected, α-branching enhances the degree of n -regioselectivity.…”

Synthesis and hydrogenation of acetonylmalonaldehyde bis(ethylene acetal)

“…3 In the study of the properties of α substituted 2,5 dimethoxytetrahydrofuran 3 carbalde hydes, 4 we have found that they are hydrolyzed by water to give acetonylmalonaldehyde and its derivatives in vir tually quantitative yields. 5, 6 To investigate this further, we studied acid catalyzed reactions of 2,5 dimethoxy 5 methyltetrahydrofuran 3 carbaldehyde (1) with alcohols.…”
