The Cu(OTf)2catalyzed Ugi-type reactions ofN,O-acetals with isocyanides have been described for the synthesis of pyrrolidinyl and piperidinyl 2-carboxamides. 4-Hydroxy-5-substituted-prolinamides can be obtained in high diastereoselectivities (2

A metal free coupling of heteroaromatic N-tosylhydrazones with thiols is presented. A convenient synthetic route to synthesize heteroaryl N-tosylhydrazones is also showed. Valuable thioethers with pyrroles, pyridines, thieno[2,3-b]pyridines, imidazo[1,2-a]pyridines, and 6H-thieno[2,3-b]pyrroles derivatives were synthesized in good yields. This coupling reaction can be carried out in a one-pot fashion and scaled up to the gram scale by using heteroaryl aldehydes, without the need to isolate the N-tosylhydrazone.

Cyclic imides were selectively reduced to the corresponding ω-hydroxylactams in high yields with (EtO)3SiH (triethoxysilane) or PMHS (polymethylhydrosiloxane) under catalysis of zinc diacetate dehydrate [Zn(OAc)2 2H2O] (10%) and tetramethylethylenediamine (TMEDA) (10%). This catalytic protocol showed good functional group tolerance as well as excellent regioselectivity for unsymmetrical imides bearing coordinating groups adjacent to the carbonyl.
