Abstract Several attempts to abbreviate our earlier syntheses of the prostaglandin intermediates 4 and 5 by photocyclisation of carbohydrate-based 1,6-dienes (15–18, 20, 22) did not yield the required bicyclo[3.2.0]heptane derivatives. Photolysis of 7- O-tert -butyldimethylsilyl-1,3,4,5,8,9-hexadeoxy-6- O -methoxymethyl- d - threo -non-3,8-dien-2-ulose (20) and ethyl 6- O-tert -butyldimethylsilyl-2
摘要通过对基于碳水化合物的1,6-二烯(15–18,20,22)进行光环化来简化我们的前列腺素中间体4和5的早期合成的几次尝试均未产生所需的双环[3.2.0]庚烷衍生物。7-O-叔丁基二甲基甲硅烷基-1,3,4,5,8,9-六脱氧-6-O-甲氧基甲基-d-苏-非-3,8-dien-2-ulose(20)和乙基的光解6-O-叔丁基二甲基甲硅烷基-2,3,4,7,8-戊氧基-5-O-甲氧基甲基-d-苏-oct-2,7-二壬酸酯(22)引起共轭烯烃键的迁移。
