The invention also provides recombinant plasmid expression vector comprising said polynucleotide sequence. The recombinant protein encoded by said polynucleotides leads to synthesis of lactones having flavour peculiar to Alphonso mangoes.

The compounds are synthesized by the selective ketalization of oxocarboxylic acids, e.g. keto acids and semialdehydes, and esters thereof with tetrols and higher polyols that products two or more cyclic ketal ester moieties per molecule, wherein the cyclic ketal moieties are situated in a bis-, tris-, or polyketal conformation. The invention further relates to applications of these compounds and subsequent reactions thereof.
参考标题:Chemo- And Regioselective Synthesis Of Acyl-Cyclohexenes By A Tandem Acceptorless Dehydrogenation-[1,5]-Hydride Shift Cascade 作者:Lewis B. Smith,Roly J. Armstrong,Daniel Matheau-Raven,Timothy J. Donohoe |发布日期:2020.2.5 摘要:Acceptorless Dehydrogenation Of The Diol Followed By A Redox-Neutral Cascade Process, Which Is Independent Of The Iridium Catalyst. Deuterium Labeling Studies Established That The Key Step Of This Cascade Involves A Novel Base-Mediated [1,5]-Hydride Shift. The Cyclohexenyl Ketone Products Could Readily Be Cleaved Under Mildly Acidic Conditions To Access A Range Of Valuable Substituted Cyclohexene Derivatives
