Example 3: The general procedure for the synthesis of (tert-butoxycarbonylmethyl)triphenylphosphonium bromide from tert-butyl bromoacetate and triphenylphosphine is as follows: In another embodiment, the functionalized lactone comprises a carboxylate protecting group as shown in Fig. 1. 10. Ylide synthesis was carried out using the following reagents and conditions: (a) triphenylphosphine (PPh3), benzene (C6H6), reaction time 12 h at room temperature (rt); (b) 20% aqueous sodium hydroxide solution (NaOH, aq), reaction time 5 h at room temperature. | [References]
