A novel divergent domino annulation reaction of prop-2-ynylsulfonium salts with sulfonyl-protected β-amino ketones has been developed, affording various epoxide-fused 2-methylenepyrrolidines and S-containing pyrroles in moderate to excellent yields. Prop-2-ynylsulfonium salts act as C2synthons in the reactions providing a promising epoxide-fused skeleton in a single operation with readily accessible starting materials.

Oxazol-2-amines were synthesized by annulation of α-amino ketones and isothiocyanates. This sequential synthetic process involves addition of α-amino ketones to isothiocyanates and I2-promoted desulfurative cyclization omitting isolation of the less stable thiourea intermediates. It is transition metal-free and operationally simple, providing access to a variety of 2-amino substituted oxazole derivatives under mild reaction conditions. (Figure presented.).

Two ss-receptor agonists (-)-denopamine and (-)-arbutamine were prepared in good yields and enantioselectivities by asymmetric hydrogenation of unprotected amino ketones for the first time by using Rh catalysts bearing electron-donating phosphine ligands. A series of α-primary and secondary amino ketones were synthesized and hydrogenated to produce various 1,2-amino alcohols in good yields and with good enantioselectivies. This Rh electron-donating phosphine-catalyzed asymmetric hyderogenation repI resents one of the most promising and convenient approaches towards the asymmetric synthesis of chiral amino alcohols.
