A New and Effective Synthetic Method for the Preparation of the Esters, Peptides, and Lactones Using 3-(5-Nitro-2-oxo-1,2-dihydro-1-pyridyl)-1,2-benzisothiazole 1,1-Dioxide. Synthesis of (±)-(<i>E</i>)-8-Dodecen-11-olide, Recifeiolide
condensing reagent. A variety of esters, dipeptides, and lactones were obtained in excellent yields. Furthermore, BID-NPy was successfully employed for the lactonization step in a new synthesis of a naturallyoccurring (±)-(E)-8-dodecen-11-olide, recifeiolide.
