Fragmentation of chloroperoxides: hypochlorite-mediated dehydration of hydroperoxyacetals to esters
摘要:
Hypochlorites efficiently dehydrate hydroperoxyacetals to furnish the corresponding esters. The reaction, which can be accomplished with stoichometric Ca(OCl)(2) or with catalytic amounts of t-BuOCl, appears to involve formation and heterolytic fragmentation of secondary chloroperoxides, species not previously described in solution chemistry.

The selective reduction of hydroperoxyacetals to aldehydes by sodium triacetoxyborohydride provides the basis for a mild one-pot synthesis of amines from alkenes. ozonolysis - hydroperoxyacetal - reductiveamination - amine - sodium triacetoxyborohydride
