Application

Propargyl p-toluenesulfonate can be used as an initiator in the synthesis of linear and cyclic poly(2-isopropyl-2-oxazoline)s by cationic ring-opening polymerization of 2-isopropyl-2-oxazoline.
It can also be used as a reagent to synthesize:
  • 2-hydroxy-4-pentynoic acid by an alkylation reaction with diethyl 2-acetamidomalonate followed by subsequent hydrolysis, decarboxylation, diazotization, and hydroxylation reactions.
  • Furan derivatives by Pd-catalyzed reaction with acylchromates.

The physicochemical properties of cyclic polymer adsorbates are significantly influenced by the steric and conformational constraints introduced during their cyclization. These translate into a marked difference in interfacial properties between cyclic polymers and their linear counterparts when they are grafted

The functional activation of Gi/o proteins coupled to muscarinic acetylcholine receptors (mAChRs) was investigated with the conventional guanosine-5'-O-(3-[(35)S]thio) triphosphate ([(35)S]GTPγS) binding assay in rat brain membranes. The most efficacious stimulation elicited by acetylcholine or carbachol (CCh) was obtained in striatal
