Transcript text: what is this molecule?

Solution

Solution Steps

Step 1: Identify the core structure

The core structure is a bicyclic system. The six-membered ring with the nitrogen atom is a pyridine ring. Fused to this is another six-membered ring.

Step 2: Identify the substituents

The pyridine ring has an amino group (-NH2) attached. The other six-membered ring is connected to a 5-membered ring containing oxygen. This oxygen is bonded to two carbons on the 5-membered ring, creating a cyclic ether. This is a tetrahydrofuran ring. The tetrahydrofuran ring is, in turn, connected to a two-carbon unit. On one end of this unit are two halogens (represented by X). At the other end, a hydroxyl group (-OH) is present.

Step 3: Put it all together

The molecule is a substituted indolizidine. The indolizidine ring system is formed by the fusion of a pyridine ring with a pyrrolidine ring. The specific isomer shown has the pyridine and pyrrolidine rings fused along the C2-C3 bond of pyridine and the C2-C3 bond of pyrrolidine. It has an amino group at position 2 of the indolizidine and a (2,2-dihalo-1-hydroxyethyl)tetrahydrofuran substituent at position 8.

Final Answer

The molecule is an indolizidine derivative, specifically 2-amino-8-(2,2-dihalo-1-hydroxyethyl)tetrahydrofuran-indolizidine where 'halo' represents an unspecified halogen atom. Drawing the structure explicitly is difficult given the lack of stereochemical information in the image.
