DEAD/PPh

The coupling of carboxylic acid 33 with alcohol 26 is performed using the Mitsunobu esterification conditions (DEAD, PPhs) to provide ester 34 with inversion of configuration at the newly formed stereogenic...

From an indole Me3P=CHCN, BnOH, 88% yield. These conditions were superior to using either DEAD/PPh or TMAD/PBui. ... 

N-Unsubstituted y-sultams can be easily substituted at the nitrogen ring by alkylation, arylation or acylation. Arylation can be performed efficiently via copper promoted chemistry by using arylboronic acids. Alkylation is usually performed with halogen derivatives by using bases such as K2CO3, NaH, TEA. In some cases good results were obtained from hydroxy substituted compounds and DEAD/PPhs [59,60]. 

Reaction of sodium azide with alcohols using DEAD/PPhs, PPhs, BF3-Et20, or Zeolites can be used to form azides. Similarly, alkyl halides in ionic liquids or under other conditions, " " chlorocyclodextrin, and certain amines can be reacted with sodium azide to form organic azides as outlined in eqs 35-40.
