Biotransformation of diterpenes and diterpene derivatives by Beauveria bassiana ATCC 7159
Phytochemistry, 2001The biohydroxylation of stemodin and stemodinone by Beauveria bassiana ATCC 7159 gave exclusively 2alpha,13,18-trihydroxystemodane and 13,18-dihydroxystemodan-2-one respectively. Stemarin was converted to the novel 1beta,13,19-trihydroxystemarane and 13-hydroxystemarane-19-carboxylic acid.

The Biosynthesis of the Diterpenes
1971The diterpenes contain a variety of structural types and functional groups which have provided a rich source of biogenetic speculation. Over the last decade biosynthetic evidence has been accumulating to support and modify some of these speculations. It is our purpose to review some of this evidence in this chapter.

Bacterial Diterpene Biosynthesis
Angewandte Chemie International Edition, 2019AbstractThis Minireview summarises recent developments in the biosynthesis of diterpenes by diterpene synthases in bacteria. It is structured by the class of enzyme involved in the first committed step towards diterpenes, starting with type I diterpene synthases, followed by type II enzymes and the more recently discovered UbiA‐related diterpene ...

The study of terpenes is intimately connected with the development of organic chemistry. In the early years of terpene research the peculiar structures of this type of compounds posed formidable problems for which methods of attack had to be invented; and the organic chemist of today owes a great deal to the pioneers in this field such as Wallach ...

At least 2500 diterpenes are found in a large number of plant families (Banthorpe and Charlwood, 1980; Croteau and Johnson, 1981; Devon and Scott, 1972; Gershenzon and Croteau, 1991; Hanson, 1991). Most of these compounds fit into about 20 major groups (Fig. 22.1).
