Patent ID: 8841477

Claim:
A process for preparing a compound of Formula I wherein each Y and each Z when present is independently selected from: —O, —O(C═O), —(C═O)—O, —O—(C═O)—O, —O—(C═O)—NH, —O—(C═O)—NR, —NH—(C═O)—O, —NR—(C═O)—O, —NH—(C═O), —NR—(C═O), —(C═O)—NH, —(C═O)—NR, —NH, —NR, N-containing heterocylic ring, —S, and halogen; each n and each m is independently the value of: 0, 1, 2, 3, 4, or 5; each A and each B when present is independently selected from: H and R, wherein when any Y or Z is —O, then A and B may also be selected from R, H, and P; V and W are H; each R when present is independently selected from: alkyl, aryl, and aralkyl; each P when present is an alcohol protecting group; and pharmaceutically and cosmetically acceptable salts thereof and diastereoisomers of the foregoing; comprising the step of coupling a benzoyl halide compound of Formula IC wherein X is halogen, with a 4-substituted styrene compound of Formula IE with a transition metal catalyst, N-heterocyclic carbene-type ligand and a first base.
