英文摘要: A direct entry to spirocycles with low to moderate regioselectivity was achieved by triphenylphosphine-catalyzed [3+2]-cycloaddition of active exo-methylenecycles(1) and ethyl 2,3-butadienoate (2). The regioselectivity of the reaction was greatly improved by using the bulky tert-butyl ester of te 2,3-butadienoate (5).The regioselectivity of the reaction was further enhanced by using the tert-butyl 2-butynoate as the substrate. This protocol provided an efficient entry to the skeleton of spirocarbocycles, especially spir[4.n]alkanes
