Descrizione generale

3-Methyl-1-pentyn-3-ol acts as initiator during the synthesis of propargyl-terminated polylactide by bulk ring-opening polymerization[1].

Applicazioni

3-Methyl-1-pentyn-3-ol is propargyl alcohol that can be used as:
  • A reactant to synthesize α-methylene cyclic carbonates by reacting with carbon dioxide.[2]
  • A reactant in the synthesis of 2,6,9-trisubstituted purine based CDK inhibitors.[3]
  • An initiator in the synthesis of polylactide bearing terminal propargyl group via ring-opening polymerization of L-lactide.[1]

Azioni biochim/fisiol

3-Methyl-1-pentyn-3-ol is a sedative and induces hepatic P4503A in mouse[4].

Reactions of propargylic alcohols with CO(2) in a [BMIm][PhSO(3)]/CuCl catalytic system to produce the corresponding alpha-methylene cyclic carbonates were conducted with high yields. Mild reaction conditions, enhanced rates, improved yields, and recyclable ionic liquid catalyst systems are the remarkable features
