Preparation of both enantiomers of an α-hydroxy ketone via biocatalytic reduction and chemical oxidation - ScienceDirect
2-Hydroxy-2,6,6-trimethylcyclohexanone 1 is a key intermediate for the synthesis of of course occurring bioactive metabolites, that is to say Both enantiomers of this key intermediate 1 were obtained by sterospecific chemical reaction using Bakers' yeast subordinate nonfermenting conditions followed by chemical oxidation. emancipated as well as immobilized cells were tested in liquid and organic media for their knowledge to catalyze the sterospecific reduction of the parent organic compound 1. preparatory scale leaf biotransformation of 1 in binary compound medium using escaped cells of Bakers' fungus produced two diastereomeric alcohols 4 and 5 at a ratio of roughly 1 :4 and 9.1% and 36.4% material yields, respectively.
For George, age 60, of Raleigh, North Carolina, quitting marijuana was no problem. He began using marihuana in college, sometimes sometime all other day, sometimes once all twosome of months, and he kept mistreatment later on graduation. “It’s recreational,” he said in an interview with Healthline.
