Steps:
6.1 4.6. Synthesis of Isoosajin (14) and isopomiferin (16)
General procedure: Isoosajin (14) and isopomiferin (16) were synthesized by adaptingthe procedure reported by Wolfrom et al. [13]. The reactions werecarried out on the opportune intermediates, which were previouslyisolated from M. pomifera fruits according to a previously reportedprocedure [9]. To perform the cyclization reaction, a round bottomflask was charged with osajin or pomiferin and 7 mL of glacial aceticacid. The mixture was heated to 100 °C and, subsequently, 0.2 mL ofsulfuric acid were added dropwise. The mixture was stirred at roomtemperature and the reaction was monitored by TLC (hexane/ethylacetate 1:1). The reaction was quenched by pouring the mixture in coldwater. The resulting solid was collected by filtration to give the desiredproduct.
