The present work demonstrates the ability of carboxylic acid tethered cyclopropanated oxabenzonorbornadienes (CPOBDs) to undergo ring-opening reactions in mild acidic conditions. The optimized reaction conditions involve the use of pTsOH in DCE at 90 °C. Two regioisomers are formed but the reactions are highly regioselective towards type 3 ring-opened products. It was observed that substitution at the C5 and aryl positions of CPOBD significantly hinders the ring-opening reactions leading to decreased yields of ring-opened products, although high regioselectivity for the Type 3 ring-opened products is still maintained. Herein, the first examples of acid-catalyzed intramolecular ring-opening reactions of CPOBD with carboxylic acid nucleophiles are reported.

Paragraph 0042-0045, (2021/09/26)
The invention relates to the technical field of photoresist and discloses a degradable resin monomer synthesized from 2 - cyclopentylcyclopentanone and a preparation method and application thereof. Wherein R is an alkyl group or a heteroalkyl group. Under the action of the acid, the tert-butyl structure is broken, so that the edge roughness of the photoresist is improved, the resolution of the photoresist is improved, the dissolution in the developing process is improved, the dissolving speed of the photoresist in the developing solution is increased, and the contrast of the photoresist is increased.
