Abstract
An efficient procedure for the synthesis of 3,5-disubstituted pyrazoles has been achieved through cyclocondensation reaction of 1,2-allenic ketones and hydrazines under extremely mild conditions. As an application, this methodology provides a highly efficient route to 5-(5-methyl-pyrazol-3-yl)-2′-deoxycytidine.
This study demonstrates a highly efficient method for synthesis of 3,5-disubstituted pyrazoles under mild conditions, providing a route to 5-(5-methyl-pyrazol-3-yl)-2′-deoxycytidine.
