Area of Science:

• Organic Chemistry
• Polymer Science

Background:

• Growing demand for biodegradable and biocompatible polymers.
• Need for versatile synthetic routes to functionalized monomers.

Purpose of the Study:

• To develop an improved two-step synthetic route to functionalized cyclic carbonate monomers.
• To introduce a novel cyclic carbonate intermediate with an active pentafluorophenyl ester group (MTC-OPhF(5)).

Main Methods:

• Synthesis of the MTC-OPhF(5) intermediate in one high-yielding step.
• Substitution reactions of the MTC-OPhF(5) intermediate with various nucleophiles (alcohols, amines).
• Demonstration of tolerance to diverse functional groups via thiol-ene click chemistry and alkyl halides.

Main Results:

• Successful synthesis of MTC-OPhF(5) on gram to kilogram scale.
• High-yielding synthesis of functionalized cyclic carbonates from the MTC-OPhF(5) intermediate.
• Broad functional group tolerance in the substitution reactions.

Conclusions:

• The developed methodology offers a simple and versatile platform for synthesizing novel functionalized cyclic carbonates.
• This approach facilitates the creation of new biodegradable and biocompatible polymers.
• The MTC-OPhF(5) intermediate is stable, easy to handle, and amenable to diverse chemical modifications.
