Description

General description

1,5-Dibromopentane is a growth supplement for Yarrowia lipolytica 3589, a tropical marine yeast.

Application

1,5-Dibromopentane can be used to prepare:

• Derivatives of 5-pyrazolones.
• O-alkylated phloroglucinol derivatives, which forms the core of poly(alkyl aryl ether) dendrimers.
• Intermediate for dezocine viz, (R)-(+)-1-(5-bromopentyl)-1-methyl-7-methoxy-2-tetralone using 1-methyl-7-methoxy-2-tetralone.

1,5-Dibromopentane was used in the preparartion of 1,5-di-Grignard reagent. It was also used in the synthesis of novel spirocyclic pyrrolidones.
