An efficient and practical synthesis of optically active indan-2-ols 1 has been developed starting from readily accessible optically active 4-siloxy-1,6-alkadiynes 2 and ethynyl p-tolyl sulfone, where the metalative Reppe reaction mediated by an economical divalent titanium reagent, Ti(O-i-Pr)(4)/2 i-PrMgCl, is

A universal, practical and scalable organocatalytic hydrocyanation manifold to provide β-substituted acrylonitriles bearing an electron-withdrawing functionality has been implemented. The catalytic manifold operates under the reactivity generation principle "a good nucleophile generates a strong base", and it uses 1,4-diazabicyclo[2.2.2]octane (DABCO)

The use of the 2-(4-methylphenylsulfonyl)ethenyl (tosvinyl, Tsv) group for the protection of the NH group of a series of imides, azinones (including AZT), inosines, and cyclic sulfonamides has been examined. The Tsv-protected derivatives are obtained in excellent yields by conjugate

A library of potential antifungal triazole-modified beta-methoxyacrylate analogues was designed and synthesized via a Cu(I)-catalyzed 1,3-dipolar alkyne-azide coupling reaction or 'click chemistry'. Subsequent biological screening revealed that some compounds displayed low to moderate antifungal activity toward pathogenic fungi and low
