The decay channels , are investigated for extracting weak Cabibbo-Kobayashi-Maskawa (CKM) phase information. These channels are described by color suppressed tree diagrams only and are free from penguin contributions. The branching ratios for these channels are found to be {approx}O(10{sup -5}-10{sup -6}) which can be measured at the currently running B factories. The method presented here may be well suited to determine the CKM angle {gamma}.
