摘要:
The present invention relates to a process for the preparation of threo-3,4-epoxy-2-amino-1-substituted butane derivatives represented by general Formula I which comprises reacting compound of Formula III or salt thereof with an active ester of acid of Formula IV and treating the product thereof with base. The carbon atom bonded to the radical R3 in Formula I and IV is in the (R)-, (S)- or (R,S)-configuration. The compounds of Formula I and III, particularly in their (2S,3R) configuration are useful intermediates for the preparation of atazanavir bisulfate.

A multiply accumulate unit (“MAC”) that performs operations on packed integer data. In one embodiment, the MAC receives 2 32-bit data words which, depending on the specified mode of operation, each contain either four 8-bit operands, two 16-bit operands, or one 32-bit operand. Depending on the mode of operation, the MAC performs either sixteen 8×8 operations, four 16×16 operations, or one 32×32 operation. Results may be individually retrieved from registers and the corresponding accumulator cleared after the read cycle. In addition, the accumulators may be globally initialized. Two results from the 8×8 operations may be packed into a single 32-bit register. The MAC may also shift and saturate the products as required.

A client computing device registers an email address as an identifier for online communication sessions. An email validation request message is received from the client computing device to validate an email address that includes the email address and an online communication session profile identifier that identifies an online communication session profile of a user of the client computing device. Responsive to determining that the email address has been validated, an email validated success message is sent to the client computing device. An activated email address request message is received from the client computing device that includes the email address and the online communication session profile identifier. The email address is then activated as an identifier associated with the online communication session profile to be used for online communication sessions.

Provided are computer implemented methods and systems for structuring information of email messages. An exemplary method comprises receiving an incoming email message. An automatic response is sent to a sender of the incoming email message with a request for information. The requested information is received from the sender and associated with a bin. The bin is structured according to a data model associated with the bin.
