Cycloaddition Reactions of (Diethylphosphono)ketenes

Methyl- and chloro(diethylphosphono)ketenes were found to add to cyclopentadiene or imines in unusual manner in the certain cases.Some chemical conversions and the Horner-Wittig reaction of the cycloadducts were examined.

Synthesis and Stereochemistry of 3-(α-Hydroxybenzyl)-1,4-diphenyl-2-azetidinones

Aldol reaction between benzaldehydes and 1,4-diphenyl-2-azetidinones 1 catalyzed by lithium diisopropylamide results in formation of the title compound The reactions give satisfactory yields and high diastereoselectivity at three centres in forming the αS
