| titleOfInvention | Process for the production of cannabidiol and delta-9-tetrahydrocannabinol |
| abstract | A process for the preparation of a compound of formula (I) **(See formula)** wherein a is an integer from 0 to 3; R1 and R2 are each independently selected from the group consisting of H, OH, protected hydroxyl, alkyl, alkenyl, alkynyl, acyl, aryl, heteroaryl, cycloalkyl, or heterocycle; wherein the alkyl, alkenyl, alkynyl, or acyl is optionally substituted with one or more substituents independently selected from the group consisting of halogen, -OH, alkyl, -O-alkyl, NRARB, -S-alkyl, -SO-alkyl, - SO2-alkyl, alkenyl, alkynyl, aryl, heteroaryl, cycloalkyl, or heterocycle; wherein RA and RB are each independently selected from hydrogen and C1-4 alkyl; wherein the aryl or heteroaryl, either alone or as part of a substituent group, is optionally substituted with one or more substituents independently selected from the group consisting of halogen, -OH, alkyl, -O-alkyl, -COOH, -C (O)-C1-4 alkyl, -C(O)O-C1-4 alkyl, NRCRD, -S-alkyl, -SO-alkyl, and -SO2-alkyl; wherein RC and RD are each independently selected from hydrogen and C1-4 alkyl; R3 is selected from the group consisting of H, alkyl, acyl, -SO2-alkyl, -SO2-aryl, and -SO2-heteroaryl; wherein alkyl is optionally substituted with one or more substituents independently selected from the group consisting of halogen, -OH, alkyl, -O-alkyl, NRERF, -S-alkyl, -SO-alkyl, -SO2-alkyl, aryl and heteroaryl; and wherein RE and RF are each independently selected from hydrogen and C1-4 alkyl; wherein the aryl or heteroaryl, either alone or as part of a substituent group, is optionally substituted with one or more substituents independently selected from the group consisting of halogen, -OH, alkyl, -O-alkyl, NRGRH, -S- alkyl, -SO-alkyl and -SO2-alkyl; wherein RG and RH are each independently selected from hydrogen and C1-4 alkyl; each represents a single or double bond; provided that both groups are not double bonds, and where denoted, dash marks indicate the points of attachment; or a pharmaceutically acceptable salt or ester thereof; the process comprises reacting a compound of formula (II), wherein each X is independently selected from the group consisting of Br, F and Cl, with a compound of formula (III) wherein R0 is H or OH, in the presence of a protic or first Lewis acid catalyst to form a compound of formula (IV); **(See formula)** then (i) cyclizing the compound of formula (IV) by reacting the compound of formula (IV) with a second Lewis acid catalyst to form a compound of formula (V); and then **(See formula)** reacting the compound of formula (V) with a reducing agent to form the compound of formula (I) **(See formula)** (ii) reacting the compound of formula ( IV) with a reducing agent to form a compound of formula (VI); and then **(See formula)** cyclizing the compound of formula (VI) by reacting the compound of formula (VI) with a second Lewis acid catalyst to form the compound of formula (I). |
