has a higher affinity to CB1/CB2 receptors than the natural stereoisomer. We have developed an inexpensive, stereoselective route to access ent-CBD derivativesusing (+)-carvone as a starting material. In addition to (+)-CBD, we report the first syntheses of (+)-cannabidivarin, (+)-cannabidiphorol as well as C-6/C-8 homologues.

The present invention provides a modifier for aromatic polyesters which enhances the melt fluidity of aromatic polyesters without a significant decrease in the heat resistance of the aromatic polyesters, and an aromatic polyester resin composition including the modifier for aromatic polyesters. The present invention relates to a modifier for aromatic polyesters comprising polyhydric phenol residues and residues of aromatic polycarboxylic acid, acid halide or acid anhydride thereof, and the modifier comprises a material having a structure composed of a first residue selected from the group consisting of divalent residues represented by Formula (I): —Ar—W

Herein are described apparatus and processes for the preparation of cannabinoids, such as cannabidiol (CBD) and derivatives thereof. The apparatus and processes described can be used for the one-step, flow-mediated synthesis of cannabidiol and derivatives with improved overall yield, material throughput, and product purity relative to batch processes.
Cannabinoid derivatives that exhibit specificity for the CB

interesting biological activities have been found as constituents of plants and plant seeds. The most prominent is primin, the n-pentyl derivative, which is stored in trichomes on leaves and stems of Primula obconica and is responsible for primrose dermatitis. The biosynthesis of primin was studied by feeding experiments with radioactively labelled precursors and unlabelled homologues.
