A small scope was investigated for this deprotection (Table ). The deprotection of the PMB was tolerable to both electron deficient (13b, and 15b) ring systems as well as electron rich (12b), ring systems. Amides were tolerable, as well as pyridine and thiophene heterocycles (17b and 18b). Alcohols were also well tolerated (14b). Alkyl benzyl sulfinates were also deprotected cleanly (19b).
