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 Synthesis of the chiral synthon for the enantioselective syntheses of the eburnamine type alkaloids, published in 1982-08-01, which mentions a compound: 32780-06-6, mainly applied to eburnamine synthon chiral enantioselective, Synthetic Route of C5H8O3.
A chiral synthon (I) for the syntheses of (-)-eburnamonine (II) and related eburnamine type alkaloids has been prepared in a good yield from the known compound (III) originated from L-glutamic acid or D-mannitol.
Compounds in my other articles are similar to this one((S)-5-(Hydroxymethyl)dihydrofuran-2(3H)-one)Synthetic Route of C5H8O3, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
