Photolysis of optically active aminocarbene chromium complexes with N-protected imidazolines produced α-amino-N-protected azapenams in good yield and with high diastereoselectivity. Removal of the protecting group resulted in cleaving of the β-lactam to give N-acylimidazolines.
光学活性氨基卡宾铬配合物与N-保护的咪唑啉的光解产生了高收率和高非对映选择性的α-氨基-N-保护的氮杂庚烷。除去保护基导致β-内酰胺裂解,得到N-酰基咪唑啉。
