Knapp and Sharma

Knapp and Sharma [79] reported a very short synthesis of miltirone (197) and this is described in Fig. (24).

Snyder observed the o-quinone dienophile reported by Knapp et. al. Sharma [79] was very unstable and thus the yield of miltirone was poor. In order to improve the yield of miltirone, it was planned to prepare o-quinone dienophile in situ. This plan was carried out by heating a mixture of 3-isopropyl-1,2-dihydroxybenzene (201), 6,6-methyl-l-...
