UV-irradiation of the aldehyde 1 leads to the 7-epimeric cyclobutanols 2a and 2b which undergo upon treatment with NaOCH3 retroaldol-like cleavage to 1 and 3. Oxidation and deacetylation of 3 affords the 16,17-dihydro-Δ15-gibberellin-A3 (5).
醛1个通向7-差向异构体cyclobutanols 2a和2b,其在治疗与经历的NaOCH的UV照射3 retroaldol样切割为1和3的氧化和脱乙酰化的3次,得到16,17-二氢Δ 15 -gibberellin -A 3(5)。
