Descrição geral

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

Aplicação

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.

Ações bioquímicas/fisiológicas

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

A titrimetric method is described for the determination of three acetylenic hypnotics, namely ethchlorvynol, ethinamate, and methylpentynol carbamate, in bulk and in dosage forms. The method involves the use of either 1,3-dibromo-5,5-dimethylhydantoin (DBH), N-bromosuccinimide (NBS) or N-bromophthalimide (NBP) as titrants.

1. Colupulone, a constituent of hops, was shown to be a potent inducer of hepatic P4503A in mouse. The olefin, 2-methyl-3-buten-2-ol (RC = CH2), is formed from lupulones when hops are exposed to atmospheric hydroxyl radicals. This suggested the possibility
