A two-step procedure is described to access 3-alkoxycyclobutanones from chloroacetyl chloride utilizing a step-wise [2+2] ketene cycloaddition followed by catalytic hydrogenation to reduce the α-chlorine in a single reaction sequence. The resulting cyclobutanones can be readily converted into a variety of cis or trans-1,3-disubstituted aminocyclobutanols and cyclobutanediols.
描述了一个分两步的程序,该过程使用逐步的[2 + 2]烯酮环加成反应从氯乙酰氯中获得3-烷氧基环丁酮,然后进行催化加氢以在单个反应序列中还原α-氯。所得环丁酮可以容易地转化成各种顺式或反式-1,3-二取代的氨基环丁醇和环丁二醇。
