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. From our findings, 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 methodology investigations is described.
