✦ Synopsis

Selective Deprotection of Triethylsilyl Group in the Presence of t-Butyldimethylsilyl Group with MCM-41/MeOH Heterogeneous System.

-The mesoporous silica MCM-41 is found to be an efficient catalyst for the selective deprotection of triethylsilyl ethers in the presence of tert-butyldimethyl silyl ether groups. The results are rationalized by the assumed mild acidity of MCM-41. -(ITOH, AKICHIKA; KODAMA, TO-
