In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Baker’s yeast reduction of β-keto esters in petrol, published in 1996-03-04, which mentions a compound: 53562-86-0, mainly applied to yeast reduction keto ester; hydroxy ester preparation, COA of Formula: C5H10O3.
A none fermenting suspension of Baker’s yeast in petrol containing a small amount of water reduces a variety of β-keto esters to the corresponding optically active β-hydroxy esters. E.g., RCOCH2CO2Et (R = Me, Et, Pr) gave (S)-RCH(OH)CH2CO2Et.
Although many compounds look similar to this compound(53562-86-0)COA of Formula: C5H10O3, numerous studies have shown that this compound(SMILES:C[C@H](O)CC(OC)=O), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
