Abstract:
Gene duplication significantly contributes to the diversification of biosynthetic potential and increases the structural diversity of secondary metabolites. Here, we report the second alkyl salicylaldehyde derivative biosynthetic gene cluster in Penicillium roqueforti, being responsible for the formation of ethanolamine-containing derivatives. Heterologous expression and feeding experiments provided evidence for their formation via collaboration and modification with one cytochrome P450 and two flavin-containing monooxygenases in a highly ordered manner before and after ethanolamine incorporation.

Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of...
