In this paper we describe the molecular and crystal structures of the K3[Y(NTA)2(H2O)] · 6H2O(H3NTA = nitrilotriacetic acid). The crystal data are as follows:
In this paper,we report the tandem Michael addition-elimination reactions of chiral 5-alkoxy-3,4-dihalo-2 (SH)-furanones with DMF by the catalyst of metal sodiu
