    摘要: A method of synthesizing a compound having the formula 1 via a cascade radical 4null1 annulation includes the step wherein the precursor 2 is reacted with an arylisonitrile having the formula 3 wherein X is a radical precursor such as Cl, Br or I. R6 is preferably nullSi(R8R9R10) or null(R7)Si(R8R9R10), wherein R7 is an alkylene group, an alkenylene group, or an alkynylene group; and R8, R9 and R10 are independently a C1-10 alkyl group, a C2-10 alkenyl group, a C2-10 alkynyl group, an aryl group or a null(CH2)NR11 group, wherein N is an integer within the range of 1 through 10 and R11 is a hydroxy group, alkoxy group, an amino group, an alkylamino group, a dialkylamino group, a halogen atom, a cyano group, nullSRc or a nitro group. R1-R4 can be broadly substituted. R5 is preferably a C1-10 alkyl group, an alkenyl group, an alkynyl group, or a benzyl group. R13 is preferably H, F or nullCH3. R16 is R16 is nullC(O)Rf or H. The E-ring (the lactone ring) may be opened.
