First, when operating the DABCO-catalyzed Ireland-Claisen rearrangement of propargylic acrylates 18b-d, we added dienophiles 40a-f in the reaction system to capture the rearranged allenes products respectively. The Diels-Alder adducts 41a-i were obtained with complete regioselectivity. Thus a novel tandem Ireland-Claisen rearrangement /Diels-Alder reaction process with propargylic acrylates has been developed.

There were 15 pediatric ALL patients, which had received 50 times of chemotherapy with HD-MTX. The records about blood concentration of MTX and clinical conditions for 50 times chemotherapy were divided into two groups. Group I: contained 25 records of stand-risk patients, administering MTX 3.0g/m2; Group II: contained 25 records of mid and high-risk patients, administering 5.0g/m2. Continuous intravenous dripped MTX for 24th in both two groups, while implemented hydrating and alkalizing for 4 days. All patients were rescued 6 times through leucovorin, 15mg/m~2, since 12th after the end of MTX dripping. Then examined the blood concentration of MTX by fluorescence polarization immunoassay approach at 24h, 44h, 68h, at the same time inspected liver function, blood routine examination, the occurrence time and degree of toxicological reactions.
