(>99% de) of 3R (or S) 3,4-disubstituted 4-pentenals into the corresponding 3,4-cis(or trans)-disubstituted cyclopentanone and highly enantioselective cyclization (>99% ee) of 4-substituted 4-pentenals into 3-substituted cyclopentanone were achieved by using cationic Rh+(BINAP)ClO4−.
3R(或S)3,4-二取代的4-戊烯的非对映选择性环化(> 99%de)转化为相应的3,4-顺(或反式)-二取代的环戊酮和4的高度对映选择性环化(> 99%ee) -取代的4-戊烯醛为3-取代环戊酮通过使用阳离子铑达到+(BINAP)CLO 4 - 。
