5-H-1,2-Oxaphosphole 2-oxides, key building blocks for diversity oriented chemical libraries

A simple and effective preparation of 2-hydrogeno-5H-1,2-oxaphosphole 2-oxides 9a–b has been developed involving direct cyclization of H-phosphinic allenes. H-1,2-Oxaphospholenes 9a–b showed to be excellent building blocks for diversity oriented small che

Reactions of 1,2-Oxaphospholenes. 4. Responses toward Oxidations, Cycloadditions, and Conjugate Additions

In contrast to the more normal reactivity of the carbon-carbon double bond in vinyl phosphonates, the oxaphospholene double bond in 5,5-dimethyl-2-phenyl-1,2-oxaphosphol-3-ene 2-oxide (7) has proven to be quite resistant to a broad spectrum of reagents in
