Intramolecular chirality transfer [2 + 2] cycloaddition of enantiomerically enriched allenoates and alkenes is presented. The use of a chiral catalyst was found to be critical to achieve high levels of diastereoselectivity compared to use of an achiral catalyst. The method developed leads to highly substituted cyclobutanes that would be difficult to prepare by alternative methods.
Selective synthesis of organophosphites

Page 6, (2008/06/13)
Disclosed herein is a process for the selective synthesis of triorganophosphites intermediates, including chloridites and dichloridites, from PX3 (X=Cl, Br or I), alcoholos and triorganoamines where alcohol and triorganoamine are added either (a) separately and concurrently, or (b) alternating equimolar portions of amine and alcohol.

Various disubstituted phosphonates including alkylnucleoside 3'-phosphonates were converted rapidly into the corresponding phosphorochloridites by use of tris(2,4,6-tribromophenoxy)dichlorophosphorane (BDCP) as a chlorinating reagent.The reaction was found to be applicable to the rapid and practical synthesis of oligonucleotides.
