TL;DR: In this paper, it was shown that the highest optical yields (up to 40%) in reactions of butyllithium with aldehydes are obtained when mixtures of (−)-1,2,3,4,4-tetramethoxy-butane (4b), (+)-2, 3-dimethoxy (N, N,N,N′,N+) with pentane are used at temperatures down to −150° and ratios of auxiliary/butyllithium of up to 10:1 (see equation (1, Tables

The preparation of 5-hydroxymethyl-2-furaldehyde (HMF) from d-fructose in the presence of DMSO
Richard M. Musau,R. M. Munavu +1 more
TL;DR: In this paper, 5-hydroxymethyl-2-furaldehyde (HMF) was produced in 92% yield when d -fructose was dehydrated using dimethylsulphoxide (DMSO) at 150°C for 2 h. The optimum conversion occurred at a d -Fructose: DMSO molar ratio of 8.0.
