An oxidative Pd-catalyzed intra-intermolecular dioxygenation of (aza-)alkenols has been reported, with total regioselectivity. To study the stereoselectivity, different chiral ligands as well as different hypervalent-iodine compounds have been compared. I

3-Aza-5-alkenols undergo selective 7- endo - trig cyclization when treated with a catalytic Pd(II) species, CuCl 2 and ArSnBu 3 giving 7-aryl-substituted oxazepanes. The intramolecular alkoxylation occurs with formation of a seven-me

A mild and efficient transition metal-free approach has been developed for the synthesis of highly substituted chiral morpholines from alkenols by amino acid-derived iodine(III) reagents via a 6-exo-trig cyclization. The key features of this work include
I2-mediated diversity oriented diastereoselective synthesis of amino acid derived trans-2,5-disubstituted morpholines, piperazines, and thiomorpholines

Diastereoselective trans-2,5-disubstituted amino acids derived diverse morpholines, piperazines and thiomorpholines were prepared in 30 min-1 h with high yields through iodine-mediated 6-exotrig type cyclization from a single common synthetic intermediate. The displacement of iodine with hydride ion gave a methyl substituent at the 2-position of morpholines which provides an additional opportunity for diversity oriented nucleophilic substitution on the rings as well as incorporation of substituents at the 5-position from amino acids constituents.
