PMB Protection - PMB-Cl - Common Organic Chemistry
Example 1. To a solution of the SM (1 g, 5.81 mmol) in DMF (10 mL) at 0 C was added NaH (512 mg, 12.8 mmol). PMBCl (2.09 g, 13.37 mmol) was added, and the mixture was stirred at RT for 2 h. The mixture was diluted with H2O (50 mL) and filtered. The resulting material was purified by silica gel chromatography (10:1 PE/EtOAc) to provide the product as a yellow oil. ... Access Full Source

Protecting Group - Wikipedia
A protecting group or protective group is introduced into a molecule by chemical modification of a functional group to obtain chemoselectivity in a subsequent chemical reaction. It plays an important role in multistep organic synthesis.. In many preparations of delicate organic compounds, some specific parts of their molecules cannot survive the required reagents or chemical environments. ... Read Article
