title: Total synthesis of siphonazoles by the use of a conjunctive oxazole building block.
abstract: The preparation of 4-carbethoxy-5-methyl-2-(phenylsulfonyl)methyloxazole and its use in the elaboration of more complex oxazoles are described. A total synthesis of the unique natural products, siphonazoles A and B, illustrates an application of the new building block.
