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 Chiral, biomimetic total synthesis of (-)-aplysistatin, published in 1982-11-05, which mentions a compound: 58081-05-3, mainly applied to aplysistatin Aplysia stereoselectivity total synthesis; cyclization biomimetic hydroxyhomogeranylbutyrolactone, Formula: C4H6O3.
The marine antineoplastic agent aplysistatin (I), from Aplysia angasi, was prepared enantiospecifically in 6 steps from R-(+)-malic acid. The key step was the biomimetic cyclization of lactone II with 2,4,4,6-tetrabromocyclohexa-2,5-dienone in MeNO2 at 20° for 2 h to give a 19:81 mixture of dihydroaplysistatins III (β-Br, β-Me, α-H; α-Br, α-Me, β-H).
There is still a lot of research devoted to this compound(SMILES：O=C1OC[C@H](O)C1)Formula: C4H6O3, and with the development of science, more effects of this compound(58081-05-3) can be discovered.
