Stereochemical aspects of high-pressure [4+2] cycloaddition between 1-methoxybuta-1,3-diene and N-protected α-amino aldehydes are discussed. In addition, the zinc bromide catalyzed cyclocondensation of 1-ethoxy-3-silyloxybuta-1,3-diene and N-protected α-amino aldehydes is studied, at ambient pressure.
讨论了1-甲氧基丁1,3-二烯与N保护的α-氨基醛之间高压[4 + 2]环加成反应的立体化学方面。另外,在环境压力下研究了溴化锌催化的1-乙氧基-3-甲硅烷氧基丁1,3-二烯与N-保护的α-氨基醛的环缩合。
