An amazing development in the history of peptide synthesis and organic chemistry in general.
Historically, the very first protecting group for amino moieties, BOC, was developed by Louis A. Carpino (1927-2019) son of Italian immigrants who settled in Des Moines. It is remarkable the vastity of the impact that this reagent had in the chemistry world, and still Carpino has not yet awarded for Nobel Price - even doesn’t have a Wiki page in English((( BTW, from the Molport platform it is possible to assemble from different worldwide suppliers very nice selections of strategic BOC-protected reagents
