Abstract:	The fully functionalized nitroalkene intermediate for the total synthesis of daphnilactone has also been prepared and participated in the high yielding tandem double-intramolecular [4+2]/[3+2] cycloaddition to provide a mixture of two epimeric nitroso acetals. Ozonolysis of the cycloadducts, followed by hydrogenolysis and intramolecular acylation provided the intermediates for the total synthesis that may be elaborated to daphnilactone B. Possible routes to complete the synthesis are also discussed.
