Reformatsky Reagent Promoted Acetylation of Primary and Secondary Aliphatic Alcohols Using Ethyl Acetate as an Acetyl Donor

Ethyl acetate as an acetyl source and solvent for acetylation of alcohols by KOH

A KOH mediated mild, efficient, convenient and gram-scalable protocol for the acetylation of alcohols with EtOAc as acetyl source and solvent. Various types of alcohols were successfully transformed into according acetylated products. Good to excellent yields were offered by primary alcohols and low to moderate yields were offered by secondary alcohols.

Trimethylsilyl Esters as Novel Dual-Purpose Protecting Reagents

Trimethylsilyl esters, AcOTMS, BzOTMS, TCAOTMS, etc., are inexpensive and chemically stable reagents that pose a negligible environmental hazard. Such compounds prove to serve as efficient dual-purpose reagents to respectively achieve acylation and trimethylsilylation of alcohols under acidic or basic conditions. Herein, a detailed study on protection of various substrates and new methodological investigations is described.
