Abstract

The ring enlargement of 1-benzyl-2,5-dihydro-1H-phosphole oxide (1) via the corresponding 2-phosphabicyclo[3.1.0]hexane 2-oxide (2) afforded, depending on the conditions, the double bond isomers (A and B) of 1,2-dihydrophosphinine oxide 4 or that of 3-substituted 1,2,3,6-tetrahydrophosphinine oxides 5 and 6. Dihydrophosphinine oxides (4) were suitable starting materials for 1,2,3,4,5,6-hexahydrophosphinine oxide 7 and 1,2,3,6-tetrahydrophosphinine oxide 8 obtained by reductive approaches and for the double bond isomers (A and B) of 2-phosphabicyclo[2.2.2]octadiene 2-oxide 9 and phosphabicyclooctene oxide 10 prepared in DielsAlder cycloaddition. Precursor 9 was utilized in the fragmentation-related phosphorylation of alcohols.
