THE dextro- and the lvo-rotatory forms of tetrahydrofuryl-2-carbinol, obtained by crystallization of the brucine salt of its hydrogen phthalic ester, exhibit complex rotatory dispersion, the carbinol obtained from the (-) hydrogen phthalic ester having...
It is common knowledge that in pheromone synthesis careful control of double bonds stereochemistry is very important, since in certain documented cases1,2 the incorrect isomer acts as inhibitor of the active isomer. In some cases however, mixtures of isomers in specific ratio constitutes certain ...
2,5-Dimethoxy-2,5-dihydrofurans 1 undergo an acid-catalysed rearrangement to 2-furylcarbinol derivatives 2. The reaction shows to be higly regioselective. The diene 3 is found to be the key-intermediate, and its formation can be utilized for the one-pot preparation of 2-methoxyl-1,6-...
CONSTITUTION:A furfurals expressed by formula I (R1 is H or lower alkyl) is reacted with an acetylene-based halogenoester expressed by formula II (X is halogen; R2 is H or lower alkyl; (n) is 2-4), pref. using 1-4 times by equivalent of the compound expressed by formula I, ...
WHEREAS a variety of methods for the preparation of ethynylcarbinols from both saturated and unsaturated carbonyl compounds have been described1, we have traced only one reference2 in the literature to the preparation of diethynyl glycols, from dicarbonyl compounds and acetylene. While this work was...
