We have been made aware that the figures, tables, compounds and experimental data reported in the title paper [1] are duplicated in another publication by the same authors [2]. [...].
Selection for allyl alcohol resistance in respiratory incompetent yeast is a highly specific method for isolating functional mutations at ADHI, the gene coding for the cytoplasmic alcohol dehydrogenase, ADHI. Because of the nature of this selection scheme, the ADHI activity of such mutants is retained, but the kinetic characteristics of the enzymes are altered. The high specificity for targetin...
The title mol-ecule, C(10)H(10)O(4), is a functionalized carbonate used in the synthetic route to organic glasses. The central CH fragment of the allyl group is disordered over two positions, with occupancies in a 0.758 (10):0.242 (10)ratio. This disorder reflects the torsional flexibility of the oxygen-allyl group, although both disordered parts present the expected anti-clinal conformation, w...
Abstract Various 1‐(1‐hydroxyalkyl) paraconyl alcohols are important signaling molecules within antibiotics production in Streptomyces sp. Intending developing a flexible convergent chemical synthesis of such butanolides, zwitterionic aza‐Claisen rearrangement was chosen as reliable strategy generating the central stereotriad. Reaction enantiopure N ‐allyl pyrrolidines and 4‐phenylbutenoic acid...
The electrochemical reduction of allyl chloride is strongly catalyzed in the presence of cobalt complexes of 2,2'-bipyridine. A prominent reaction product of the catalyzed reduction is 1,5-hexadiene. Voltammetry, coulometry, and gas chromatographic data are presented and analyzed and a mechanistic scheme proposed to. account for the catalytic action of the cobalt-2,2'-bipyridine complexes. Rece...
thiophosgene and 1-chloroethyl chlorothionoformate react readily with tertiary amines, and give the dialkylamine hydrochloride after hydrolysis of the initial product with water. benzyl and allyl groups are cleaved in preference to methyl and other alkyl groups. the rection with the isoquinoline alkaloid narcotine occurs particularly easily.
