1 Source of material

Andrographolide (40 g, 114 mmol) was dissolved in a mixed solution of toluene (400 mL) and dimethyl sulfoxide (64 mL), and 4-toluenesulfonic acid (2 g, 11.6 mmol) and 2,2-dimethoxypropane (48 mL, 544 mmol) were added separately with stirring and heated to 90 °C for 4 h. Upon completion, the mixture was filtered through celite, and washed with CH2Cl2 (10 mL) and concentrated in vacuo. Then, the crude product was subjected to flash column chromatography on silica gel (petroleum ether/ethyl acetate = 1:1) to afford the product.

2 Experimental details

The carbon-bound hydrogen atoms were placed in their geometrically idealized positions and constrained to ride on their parent atoms with d(C–H) = 0.82–1.06(4) Å, U iso(H) = 1.5 times U eq(C) and 1.2 times U eq(O).

3 Comment

Andrographolide, a diterpenoid lactone [4], can be obtained from the extract of traditional herb paniculata with extraordinary efficacy. Andrographolide and its derivatives are important bioactive compounds. They have good potential for applications in fields of pharmacology [5], [6], [7]. Therefore, the synthesis and modification of Andrographolide have always been a hot topic in the medical field.

The title compound contains one diterpenoid lactone, three hydroxyl, one oxygen-containing pentacyclic, and four methyl groups. The bond lengths and angles derived from the title structure are within normal ranges and consistent with those reported previously in similar structures [810]. The C=C bond was determined at the distance of 1.320(3) Å (C13–C14). The carbonyl group was confirmed by the distance of 1.200(3) Å (C17–O5), and the alcohol hydroxyl group was identified by the distance of 1.393(4) Å (C15–O3), respectively. The oxygen-containing pentacycle with C17–O4–C16 torsion angle of 109.9 ( 2 ) . The oxygen-containing pentacycle was confirmed by the distance of 1.337(3) Å (C17–O4), distance and of 1.436(4) Å (C16–O4), respectively.
