α-Methoxy-α-(6H-1,3-thiazin-2-yl)glycinates precursors of 7-methoxycephems by [3+3] cyclocondensation reaction
摘要:
We report here a new widely useful and applicable preparation of functionalised 6H-1,3-thiazinic cycloadducts, versatile key intermediates in the total multistep syntheses of 7-methoxycephems (as analogues of 7-methoxycephalosporins).
