Patra, D., & Ghosh, S. 1994 Sequential [2+2] photocycloaddition and rearrangement to substituted cyclopentanone, a formal synthesis of planococcyl acetate.. Synthetic Communications 24(12): 1663-1668.

Notes: An extremely short synthesis of 2,2-dimethyl-3-hydroxymethyl cyclopentanone 2 (R1 = R2 = Me), an advanced intermediate in the synthesis of the pheromone planococcyl acetate 3 (citrus mealybug), is described.
