Paragraph 0143, (2020/07/31)
The disclosure relates to rexinoids, including compounds of the Formula (I) and (II) or a pharmaceutically acceptable salt, polymorph, prodrug, solvate or clathrate thereof. These rexinoids are useful for increasing PD-L1 in vivo, for treatment of cancer, and for inhibiting the onset of cancer.
Isopropylation of m-cresol over mesoporous Al-MCM-41 molecular sieves

A study on the isopropylation of m-cresol with isopropyl alcohol was carried out utilizing Al-MCM-41 molecular sieves with Si/Al ratios of 59:1, 103:1, and 202:1 at 250°-400°C. The products obtained were 2-isopropyl-5-methylphenol (IMP), isopropyl-3-methylphenyl ether (IMPE), and isopropyl-(2-isopropyl-5-methylphenyl) ether (IIMPE). The m-cresol conversion increased till 300°C, after which it decreased. The selectivity of 2-isopropyl-5-methylphenol (IMP) was more than that of the other products. Of the three catalysts studied for isopropylation of m-cresol with isopropyl alcohol in the vapor phase, AI-MCM-41 (59) was more suitable than Al-MCM-41 (103) and Al-MCM-41 (202). The feed ratio of 1:2 was more suitable for better conversion and 100% selectivity to IMP. The study of time on stream indicates the retention of activity even after 10 hr with the feed ratio of 1:4 for nearly 10% conversion. Al-MCM-41 could be a convenient and ecofriendly alternative to the hazardous and highly corrosive mineral acid catalysts for m-cresol isopropylation.
