A reasonable synthetic route was designed based on bicyclo[3.1.0]hexane skeleton. Norrish II type photochemical precursor (1R,5S)-3-hydroxybicyclo[3.1.0]hexan-6-yl(phenyl)methanone (10) was successfully synthesized. The absolute configuration of 10 was determained by means of 1H NMR, 13C NMR, DEPT135, H-H COSY, HMQC, HMBC, ROESY, 6-H-1D-NOE, 9-H-1D-NOE and HRMS. Meanwhile, the important intermediate 11 of pros-taglandins (PG) was afforded through Norrish II type photochemical reaction using 10 as substrate. As a result, 11 and 12 which possess cyclopentene structure were obtained through the characterization of NMR and HPLC. The mechanism of the photochemical reaction was also put forward.

Key words: bicyclo[3.1.0]hexane, Norrish II type photochemical reaction, prostaglandin
