一般描述

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

应用

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.
  • A reactant in the synthesis of 2,6,9-trisubstituted purine based CDK inhibitors.
  • An initiator in the synthesis of polylactide bearing terminal propargyl group via ring-opening polymerization of L-lactide.

生化/生理作用

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