Enantioselective synthesis is a process that produces a single enantiomer of a substance. This is a ketone reduction with alpine borane and is enantioselective due to it producing one of two possible alcohol enantiomers. Eracemization is the transformation of the racemate into a single stereoisomeric that has one hundred percent yield.

Research was conducted in order to enhance the synthesis of R-1,3 butanediol from the low cost racemate without wasting substrate, a steoreinverting cascade was constructed for total conversion of the racemate. The cascade reaction comprised of enantioselective oxidation of S-1,3 butanediol with asymmetric reduction.

The key reaction included a range of pH, rotation speeds and temperatures to determine whether to add acetone. Studies have also added glucose as a co-substrate at pH 8.0 and a temperature of thirty-five degrees Celsius with a two hundred rotation speed. The feasibility has been tested using a step by step method with a one pot experiment as a natural extension for performing oxidation. The step by step approach is efficient for the cascade process from racemate to R-1,3 ...
... butanediol.

The study found that the step-by-step cascade reaction was efficient in producing R-1,3 butanediol from racemate through biosynthesis, showing promise in application prospects in the future. Taking into consideration that chiral alcohols are used in medicine, food, chemical and pesticide fields with optimal activity. It is a coital pharmaceutical, especially in the synthesis of azelidionone derivatives. The demand for R-1,3 butanediol has increased exponentially over the past few years, used as antibacterial agents throughout the world.

Right now, R-1,3 butanediol is produced through chemical synthesis or microbial conversion. It has been observed that ruthenium complexes of phosphine-aminophosphine produces R-1,3 butanediol through asymmetric reduction with eighty one percent enantiomeric excess.

In some cases, dangerous reagents are necessary to ensure chemical synthesis and the reactions can be severe. Biocatalytic processes produce mild reactions by leaving no residual metals in the product. Testing involved five hundred and forty four colonies from soil samples in a two step reaction method. The first step was oxidation and the second was functional screening.

To achieve high purity, oxidation and reaction should be present and yield. Two experiments were performed with the C parasitosis racemate being gradually reduced until there was a zero concentration and then gradually increased. The R-1,3 butanediol concentration remained unchanged.

R-1,3 butanediol has proven highly effective to promote ketosis in humans without changing diet or behaviors with excellent results. The higher quality products are manufactured using natural plant sugars to ensure safety and promote the best end results. Studies are being carried out regularly to identify the safety of these products, along with the step by step reactions of the racemates.

Studies have shown that there is a serious impact on the oxidation and reduction rates with regard to pH levels. Steps were improved with a higher pH. When the pH was increased too much the yields were lower. The optimum pH for oxidation and reduction was determined at 8.0 with excellent yields.

During the studies the rotation speed was also a very important consideration in the synthesis of R-1,3 butanediol. Yields were increased when the rotation speed was boosted to two hundred revs per minute. This indicated a mass transfer with a strong influence on the reaction processes.

Overall the studies concluded that this was the first time that pure R-1,3 butanediol was produced from low cost racemate using a cascade pathway with minimal substrate wastage. The processes proved easy to use and operate,
