The combination of homo-Nazarov cyclization of 2-( tert -butyldiphenylsilylmethyl)cyclopropyl vinyl ketone leading to oxyallyl cation and its subsequent [3+2] capture by allylsilane has been demonstrated as an useful strategy for the construction of

A one-pot cascade method to obtain functionalized phenanthridine-fused quinazoliniminiums from a variety of heteroenyne-allenes is described. This protocol involves formation of C-N and C-C bonds in a single step in the presence of a Lewis acid and t

The cross aldol reaction between enolizable aldehydes and α-ketophosphonates was achieved for the first time by using 9-amino-9-deoxy-epi-quinine as the catalyst. β-Formyl-α-hydroxyphosphonates were obtained in high to excellent enantioselectiviti
