The study conducted on the population dynamics of the olive psyllid Euphyllura olivina, (Costa, 1839), on the variety Chemlal in the oases of Boussaâda, during the first half of the year 2021, showed that the first numbers of the different biologica

Baker's yeast reductions of ethyl 2-alkyl 3-oxobutanoates provided ethyl 2-alkyl 3(S)-hydroxybutanoates. Such compounds were used as sources for precursors of 2(S)-ethoxymethoxyalkyl radicals whose reactions towards halogen donors, tin hydride and me

Baker's yeast treatment of ethyl 2-chloro-3-oxobutanoate 1 , diethyl 2-acetylmalonate 2 and ethyl 2-cyano-3-oxobutanoate 3 was effected in order to obtain enantiomerically enriched compounds. In contrast to the reaction of 2 and 3 , efficient diaster

The reduction of 2-ethoxycarbonyl-cyclopentanone and-cyclohexanone by baker’s yeast yielded in good yields (IS, 2R) 2-ethoxycarbonyl-cyclopentanol and cyclohexanol. The above two hydroxyesters were used as starting materials to prepare, via free ra

Baker's yeast reduction of ethyl acetoacetate provided in good yield ethyl 2(S)-hydroxybutanoate. The hydrolysis of the ester function after protection of the hydroxyl yielded an acid which, under BARTON'S free radical decarboxylation conditions, pro
