(9S,10S)-10-Acetoxy-8,8-dimethyl-2-oxo-9,10-dihydro-2H,8H-pyrano[2,3-f]chromen-9-yl (2Z)-2-methyl-2-butenoate(CAS: 73069-27-9)

This compound is a crystalline solid with a molecular weight of approximately 408.4 g/mol. It has a low water solubility but is soluble in organic solvents like ethanol and acetone. Chemically, it is known for its reactivity, particularly with nucleophiles and electrophiles, and it can undergo various transformations such as ester hydrolysis and acetylation.

This compound is typically synthesized via a multi-step process involving acetylation of the chromenone, followed by esterification with (2Z)-2-methyl-2-butenoic acid. The synthesis involves the use of acetic anhydride and a strong acid catalyst, such as sulfuric acid, and proceeds with high selectivity and good yield.

This compound is primarily used in the pharmaceutical industry for its potential as an intermediate in drug synthesis. It may also find applications in the polymer industry, where it could be used as a monomer or crosslinking agent, and in sensors and semiconductors due to its unique chemical structure.

Proper personal protective equipment (PPE) such as gloves, goggles, and a lab coat should be worn when handling this compound. Work should be conducted in a fume hood to avoid inhalation. Spills should be cleaned up using appropriate absorbent materials and disposed of according to local regulations. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal instructions.
