General description

6-Heptynoic acid is an alkynoic acid with an acetylene bond. It undergoes condensation with various pyrroles to afford optical diverse fluorescent dyes with a terminal alkyne.

Application

6-Heptynoic acid may be used for the following syntheses:
  • alkyne functionalized Boradiazaindacenes (BODIPY)dyes
  • natural products epothilone B and D
  • hymenialdisine (HMD) and aldisine (AD) affinity resins
  • alkynyl esters

Dehydroabietic acid (DHA) is a naturally occurring diterpene with different and relevant biological activities. Previous studies have shown that some DHA derivatives display antiproliferative activity. However, the reported compounds did not include triazole derivatives. Starting from DHA (8,11,13-abietatrien-18-oic acid), and

Type I modular polyketide synthases assemble diverse bioactive natural products. Such multienzymes typically use malonyl and methylmalonyl-CoA building blocks for polyketide chain assembly. However, in several cases more exotic alkylmalonyl-CoA extender units are also known to be incorporated. In all
